PFileMailer Class

Properties   Methods   Events   Config Settings   Errors  

The PFileMailer class is used to send encrypted and/or signed plaintext-formatted emails, with any attachments, using OpenPGP.

Syntax

class ipworksopenpgp.PFileMailer

Remarks

The PFileMailer class offers an easy-to-use interface: you can send an OpenPGP signed and encrypted message using the PSMTP class by calling the encrypt, sign, and sign_and_encrypt methods. Additionally, it enables you to create messages bound for multiple recipients with different keys, simultaneously encrypt and compress with the most popular compression algorithms, and control other aspects such as the encrypting algorithm.

Construct the Message

To begin specify common email properties such as send_to, cc, b_cc, subject, and message_text. Connection information is specified by setting mail_server and mail_port.

Sign

To sign a message specify a recipient key using the Key* properties. For instance: PFileMailer1.KeyCount = 1 PFileMailer1.KeyKeyring(0) = "c:\my_keyring_dir" PFileMailer1.KeyUserId(0) = "sender@nsoftware.com" PFileMailer1.KeyPassphrase(0) = "password" The specified private key will be used to sign the message when sign is called.

Encrypt

To encrypt a message specify a recipient key using the RecipientKey* properties. For instance: PFileMailer1.RecipientKeyCount = 1 PFileMailer1.RecipientKeyKeyring(0) = "c:\my_keyring_dir" PFileMailer1.RecipientKeyUserId(0) = "recipient@nsoftware.com" The specified public key will be used to encrypt the message when encrypt is called.

Sign and Encrypt

To sign and encrypt a message in one step call sign_and_encrypt. The message will be signed with the private keys specified in the Key* properties and encrypted with the public keys defined in the RecipientKeys* properties.

Add Attachments

To add attachments simply call add_attachment. The ProcessAttachments setting specifies whether attachments are also encrypted and signed.

Send

Call the send method once the necessary properties have been set for each recipient.

attachment_count Property

The number of records in the Attachment arrays.

Syntax

def get_attachment_count() -> int: ...
def set_attachment_count(value: int) -> None: ...

attachment_count = property(get_attachment_count, set_attachment_count)

Default Value

0

Remarks

This property controls the size of the following arrays:

• attachment_file
• attachment_name

The array indices start at 0 and end at attachment_count - 1.

attachment_file Property

This property contains the path of a file on your system to be sent as an attachment with your message.

Syntax

def get_attachment_file(attachment_index: int) -> str: ...
def set_attachment_file(attachment_index: int, value: str) -> None: ...

Default Value

""

Remarks

This property contains the path of a file on your system to be sent as an attachment with your message.

The attachment_index parameter specifies the index of the item in the array. The size of the array is controlled by the attachment_count property.

attachment_name Property

This property contains the name of the attachment to be sent.

Syntax

def get_attachment_name(attachment_index: int) -> str: ...
def set_attachment_name(attachment_index: int, value: str) -> None: ...

Default Value

""

Remarks

This property contains the name of the attachment to be sent.

The attachment_index parameter specifies the index of the item in the array. The size of the array is controlled by the attachment_count property.

auth_mechanism Property

This property is used when connecting to the mail server.

Syntax

def get_auth_mechanism() -> int: ...
def set_auth_mechanism(value: int) -> None: ...

auth_mechanism = property(get_auth_mechanism, set_auth_mechanism)

Default Value

0

Remarks

This is the authentication mechanism property to be used when connecting to the mail server.

By default, this property is amUserPassword (0), and if the user and password properties are set, the AUTH command is sent to the server for authentication. If this property is set to amCRAMMD5 (1), CRAM-MD5 authentication is used instead.

If this property is set to amNTLM (2), NTLM authentication will be used.

If this property is set to amKerberos (6), Kerberos authentication will be used.

Note: This functionality is available only in Windows.

When set to amXOAUTH2 (7), set user to the username and AuthorizationIdentity to the OAuth token. See AuthorizationIdentity for details.

b_cc Property

This property includes a comma-separated list of addresses for blind carbon copies (optional).

Syntax

def get_b_cc() -> str: ...
def set_b_cc(value: str) -> None: ...

b_cc = property(get_b_cc, set_b_cc)

Default Value

""

Remarks

This property specifies a comma-separated list of destinations for blind carbon copies of the mail message. A copy of the message is sent to each destination. Because no BCc SMTP header is created containing the destination addresses, individual recipients never see the list of the other recipients.

The class will return an error if the mail_server returns an error code about any email address specified in send_to or cc but it will fire an on_error event only if the same thing happens with an email address specified in this property.

If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.

Note: You must clear the message_recipients properties before setting this property to remove previous recipients.

cc Property

This property includes a comma-separated list of addresses for carbon copies (optional).

Syntax

def get_cc() -> str: ...
def set_cc(value: str) -> None: ...

cc = property(get_cc, set_cc)

Default Value

""

Remarks

This property specifies a comma-separated list of destinations for carbon copies of the mail message. A copy of the message is sent to each destination, and a Cc SMTP header is created containing the destination addresses. This header is sent to every recipient of the message. If you don't want to copy this information to every recipient, then use blind carbon copies instead (see the description of the b_cc).

The class will return an error if the mail_server returns an error code about any email address specified in send_to or cc but it will fire an on_error event only if the same thing happens with an email address specified in b_cc.

If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.

Note: You must clear the message_recipients properties before setting this property to remove previous recipients.

The key_index parameter specifies the index of the item in the array. The size of the array is controlled by the key_count property.

key_keyring Property

The location of the keyring.

Syntax

def get_key_keyring(key_index: int) -> str: ...
def set_key_keyring(key_index: int, value: str) -> None: ...

Default Value

""

Remarks

The location of the keyring.

If the keyring is stored in a directory, set this property to the directory. The directory must contain the files "secring.gpg" and "pubring.gpg". A keyring may also be stored in a single file. If the keyring is a file this property should be set to the path of the file.

When This property is set the class will read the keyring and populate the Key* properties with the first key found in the keyring. Set key_user_id to select a different key in the current keyring.

The key_index parameter specifies the index of the item in the array. The size of the array is controlled by the key_count property.

key_passphrase Property

Remarks

The passphrase for the key's secret key (if any). This must be specified before operations requiring the secret key are attempted. The passphrase may be supplied in this property or through the on_key_passphrase event, which will fire when a passphrase is required.

The passphrase is required when using the following methods in KeyMgr:

• add_user_id
• sign_user_id
• change_expiration_date
• change_passphrase

When using the OpenPGP class, or an email-based class, the following methods require a passphrase for the key:

• decrypt
• sign
• sign_and_encrypt

The key_index parameter specifies the index of the item in the array. The size of the array is controlled by the key_count property.

key_user_id Property

The user Id of the key.

Syntax

def get_key_user_id(key_index: int) -> str: ...
def set_key_user_id(key_index: int, value: str) -> None: ...

Default Value

""

Remarks

The user Id of the key. When a key is loaded this property is populated with the user Id associated with the key. This property may be set to load a key from the keyring. When this property is set the class will search the keyring for a key associated with the UserId specified.

When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and key_other_user_ids after loading the key.

The UserId format is:

FirstName LastName (Comment) <Email>

When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The class will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP class's on_recipient_info event.

The key_index parameter specifies the index of the item in the array. The size of the array is controlled by the key_count property.

The last reply from the server.

Syntax

def get_last_reply() -> str: ...

last_reply = property(get_last_reply, None)

Default Value

""

Remarks

This property indicates the last reply received from the server. It can be used for informational purposes. The same information and more can also be retrieved through the on_pi_trail event.

This property is read-only.

local_host Property

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

def get_local_host() -> str: ...
def set_local_host(value: str) -> None: ...

local_host = property(get_local_host, set_local_host)

Default Value

""

Remarks

The local_host property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the local_host property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: local_host is not persistent. You must always set it in code, and never in the property window.

mail_port Property

The server port for SMTP (default 25).

Syntax

def get_mail_port() -> int: ...
def set_mail_port(value: int) -> None: ...

mail_port = property(get_mail_port, set_mail_port)

Default Value

25

Remarks

This property contains the server port for SMTP (default 25). A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error.

For implicit SSL, use port 465 (please refer to the ssl_start_mode property for more information).

mail_server Property

The name or address of a mail server (mail relay).

Syntax

def get_mail_server() -> str: ...
def set_mail_server(value: str) -> None: ...

mail_server = property(get_mail_server, set_mail_server)

Default Value

""

Remarks

This property specifies the IP address (IP number in dotted internet format) or Domain Name for a mail relay through which messages will be routed. It is set before a connection is attempted and cannot be changed once a connection is in progress.

The current version of the class does not provide a default value for the mail relay. You must provide a host name yourself. Generally, any internet host with an SMTP server will suffice (a UNIX host for example), but it is preferable to select a mail_server that is close to the machine sending mail.

If this property is set to a Domain Name, a DNS request is initiated and upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.

If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.

message_date Property

Date of the mail message (optional).

Syntax

def get_message_date() -> str: ...
def set_message_date(value: str) -> None: ...

message_date = property(get_message_date, set_message_date)

Default Value

"*"

Remarks

If this property contains a non-empty string, then a Date SMTP header is created and attached to the message. If it is an empty string, then the date information is added by the mail relay(s) the message goes through.

Special case: if this property is set to the special value "*", a Date SMTP header reflecting the current date and time is generated when message_headers is computed and the message is sent. This is the default behavior of the class

RFC 822 contains detailed date format specifications. An example of a valid date is "Fri, 1 Mar 96 21:24:52 EST".

message_id Property

The Message Identifier for the message.

Syntax

def get_message_id() -> str: ...
def set_message_id(value: str) -> None: ...

message_id = property(get_message_id, set_message_id)

Default Value

"*"

Remarks

This property contains the Message Identifier for the message. When set, the value of message_id is used as the Message-ID header value of the message. A special value of "*" will automatically generate a random unique identifier for the message.

message_recipient_count Property

The number of records in the MessageRecipient arrays.

Syntax

def get_message_recipient_count() -> int: ...
def set_message_recipient_count(value: int) -> None: ...

The class automatically escapes lines that start with a "." by adding another as specified in RFC 821. The message text is unescaped by the receiving agent, so the process is fully transparent.

other_headers Property

An RFC 822 compliant string consisting of extra headers.

Syntax

def get_other_headers() -> str: ...
def set_other_headers(value: str) -> None: ...

other_headers = property(get_other_headers, set_other_headers)

Default Value

""

Remarks

The headers must be of the format "header: value" as specified in RFC 822. Header lines should be separated by CRLF ("\r\n") .

Use this property with caution. If this property contains invalid headers, message delivery might not be successful.

This property is useful for extending the functionality of the class. A good example is delivery of MIME encoded messages.

SPECIAL CASE: if this property starts with an empty line (CRLF), then the value of this property is used instead of the normally computed message headers.

Example (Send an Email With Additional Header)

component.MailServer = "MyServer"; component.From = "me@server.com"; component.SendTo = "recipient@server.com"; component.Subject = "My Subject"; component.MessageText = "This is the message body."; component.OtherHeaders = "HeaderName: HeaderValue"; component.Send();

When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and key_other_user_ids after loading the key.

The UserId format is:

FirstName LastName (Comment) <Email>

When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The class will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP class's on_recipient_info event.

The recipient_key_index parameter specifies the index of the item in the array. The size of the array is controlled by the recipient_key_count property.

reply_to Property

A mail address to which to reply (optional).

Syntax

def get_reply_to() -> str: ...
def set_reply_to(value: str) -> None: ...

reply_to = property(get_reply_to, set_reply_to)

Default Value

""

Remarks

If this property contains a non-empty string, a Reply-To SMTP header is created for the message. This header shows the address to use for replies (useful if this address is different from the one in from_).

If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.

send_to Property

A comma separated list of addresses for destinations (required).

Syntax

def get_send_to() -> str: ...
def set_send_to(value: str) -> None: ...

send_to = property(get_send_to, set_send_to)

Default Value

""

Remarks

This property specifies a comma separated list of destinations for the mail message. A copy of the message is sent to each of them, and a To SMTP header is created containing the destination addresses.

Examples of valid addresses are: "Friendly Name" <address@company.com> or address@company.com

The class will fail if the mail_server returns an error code about any email address specified in SendTo or cc but it will silently ignore the error if the same happens with an email address specified in b_cc.

If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.

NOTE: You must clear the message_recipients properties before setting this property to remove previous recipients.

sensitivity Property

Sensitivity of the mail message (optional).

Syntax

def get_sensitivity() -> int: ...
def set_sensitivity(value: int) -> None: ...

sensitivity = property(get_sensitivity, set_sensitivity)

Default Value

0

Remarks

This property is an indication of how sensitive it is to disclose the message to people other than the recipients of the message. When set, a Sensitivity header will added to the message. Possible values are: esPersonal (1), esPrivate (2), and esCompanyConfidential (3).

signing_algorithm Property

The signature hash algorithm used when signing.

Syntax

def get_signing_algorithm() -> str: ...

def set_ssl_accept_server_cert_encoded(value: bytes) -> None: ...

ssl_accept_server_cert_encoded = property(get_ssl_accept_server_cert_encoded, set_ssl_accept_server_cert_encoded)

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The ssl_accept_server_cert_store and ssl_accept_server_cert_subject properties also may be used to specify a certificate.

When ssl_accept_server_cert_encoded is set, a search is initiated in the current ssl_accept_server_cert_store for the private key of the certificate. If the key is found, ssl_accept_server_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_accept_server_cert_subject is set to an empty string.

ssl_cert_encoded Property

This is the certificate (PEM/base64 encoded).

Syntax

def get_ssl_cert_encoded() -> bytes: ...
def set_ssl_cert_encoded(value: bytes) -> None: ...

ssl_cert_encoded = property(get_ssl_cert_encoded, set_ssl_cert_encoded)

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The ssl_cert_store and ssl_cert_subject properties also may be used to specify a certificate.

When ssl_cert_encoded is set, a search is initiated in the current ssl_cert_store for the private key of the certificate. If the key is found, ssl_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_cert_subject is set to an empty string.

ssl_cert_store Property

This is the name of the certificate store for the client certificate.

Syntax

def get_ssl_cert_store() -> bytes: ...
def set_ssl_cert_store(value: bytes) -> None: ...

ssl_cert_store = property(get_ssl_cert_store, set_ssl_cert_store)

Default Value

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The ssl_cert_store_type property denotes the type of the certificate store specified by ssl_cert_store. If the store is password protected, specify the password in ssl_cert_store_password.

ssl_cert_store is used in conjunction with the ssl_cert_subject property to specify client certificates. If ssl_cert_store has a value, and ssl_cert_subject or ssl_cert_encoded is set, a search for a certificate is initiated. Please see the ssl_cert_subject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

ssl_cert_store_password Property

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

Syntax

def get_ssl_cert_store_password() -> str: ...
def set_ssl_cert_store_password(value: str) -> None: ...

ssl_cert_store_password = property(get_ssl_cert_store_password, set_ssl_cert_store_password)

Default Value

""

Remarks

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

def set_ssl_cert_store_type(value: int) -> None: ...

ssl_cert_store_type = property(get_ssl_cert_store_type, set_ssl_cert_store_type)

Default Value

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used, the class will automatically determine the type. This property can take one of the following values:

ssl_cert_subject Property

This is the subject of the certificate used for client authentication.

Syntax

def get_ssl_cert_subject() -> str: ...
def set_ssl_cert_subject(value: str) -> None: ...

ssl_cert_subject = property(get_ssl_cert_subject, set_ssl_cert_subject)

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

If a field value contains a comma, it must be quoted.

ssl_enabled Property

Whether TLS/SSL is enabled.

Syntax

def get_ssl_enabled() -> bool: ...
def set_ssl_enabled(value: bool) -> None: ...

ssl_enabled = property(get_ssl_enabled, set_ssl_enabled)

Default Value

FALSE

Remarks

This setting specifies whether TLS/SSL is enabled in the class. When False (default) the class operates in plaintext mode. When True TLS/SSL is enabled.

TLS/SSL may also be enabled by setting ssl_start_mode. Setting ssl_start_mode will automatically update this property value.

ssl_provider Property

This specifies the SSL/TLS implementation to use.

Syntax

def get_ssl_provider() -> int: ...
def set_ssl_provider(value: int) -> None: ...

ssl_provider = property(get_ssl_provider, set_ssl_provider)

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

ssl_server_cert_encoded Property

This is the certificate (PEM/base64 encoded).

Syntax

def get_ssl_server_cert_encoded() -> bytes: ...

ssl_server_cert_encoded = property(get_ssl_server_cert_encoded, None)

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The ssl_server_cert_store and ssl_server_cert_subject properties also may be used to specify a certificate.

When ssl_server_cert_encoded is set, a search is initiated in the current ssl_server_cert_store for the private key of the certificate. If the key is found, ssl_server_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_server_cert_subject is set to an empty string.

This property is read-only.

ssl_start_mode Property

Determines how the class starts the SSL negotiation.

Syntax

def get_ssl_start_mode() -> int: ...
def set_ssl_start_mode(value: int) -> None: ...

ssl_start_mode = property(get_ssl_start_mode, set_ssl_start_mode)

Default Value

3

Remarks

The ssl_start_mode property may have one of the following values:

subject Property

The subject of the mail message (optional).

Syntax

def get_subject() -> str: ...
def set_subject(value: str) -> None: ...

subject = property(get_subject, set_subject)

Default Value

""

Remarks

The string in this property is sent with a Subject SMTP header to the mail recipient.

If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.

timeout Property

A timeout for the class.

Syntax

def get_timeout() -> int: ...
def set_timeout(value: int) -> None: ...

timeout = property(get_timeout, set_timeout)

Default Value

60

Remarks

If the timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use do_events to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If timeout expires, and the operation is not yet complete, the class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by timeout seconds when any amount of data is successfully sent or received.

The default value for the timeout property is 60 seconds.

user Property

A user identifier to login as in the MailServer .

Syntax

def get_user() -> str: ...
def set_user(value: str) -> None: ...

user = property(get_user, set_user)

Default Value

""

Remarks

If this property is set to a non-empty string, then when connecting to the mail_server an AUTH or CRAM-MD5 (depending on the value of auth_mechanism) command is sent in order to provide authentication information for the user.

add_attachment Method

This adds FileName as an attachment.

Syntax

def add_attachment(file_name: str) -> None: ...

Remarks

This method adds the file name as an attachment. The full list of attachments is contained in the attachments property.

Example 1: Adding an Attachment

component.AddAttachment("C:\file1.zip"); component.AddAttachment("C:\file2.zip"); component.Send(); Example 3: Using an Attachments Array

component.AttachmentCount = 1; component.AttachmentName(0) = "name"; component.AttachmentFile(0) = "C:\file.txt";

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

connect Method

This method connects to the mail relay and sends the SMTP HELO command.

Syntax

def connect() -> None: ...

Remarks

This method connects to the mail relay and sends the SMTP HELO command, thus preparing to send messages. Any number of messages can later be sent using the send method.

Example. Connecting and Sending an Email:

control.MailServer = "MyServer" control.From = "me@server.com" control.SendTo = "recipient@server.com" control.Subject = "My Subject" control.MessageText = "This is the message body" control.Connect() control.Send() control.Disconnect()

disconnect Method

This method disconnects from the SMTP server.

Syntax

def disconnect() -> None: ...

Remarks

This method disconnects from the mail relay.

do_events Method

Processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

When do_events is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

encrypt Method

Encrypts the message.

Syntax

def encrypt() -> None: ...

Remarks

This method encrypts the specified message.

The message is encrypted with the public keys specified in the RecipientKey* properties.

When encrypting, the following properties may be used to further configure the class:

• compression_method
• encrypting_algorithm

interrupt Method

Interrupt the current method.

Syntax

def interrupt() -> None: ...

Remarks

If there is no method in progress, interrupt simply returns, doing nothing.

process_queue Method

Sends the messages which have previously been queued into QueueDir .

Syntax

def process_queue(queue_dir: str) -> None: ...

Remarks

This method sends the messages which have previously been queued into QueueDir. The on_pi_trail event shows the interaction with the server as messages as are processed.

This method looks in the directory for files with extension ".queued" and starts processing them.

When processing starts, the file extension is changed to ".sending". If an error happens at this stage, the sending process is aborted, and the file extension is changed to ".failed".

If the file is successfully sent, the file is normally deleted, unless the KeepQueue configuration setting is set to True, in which case the file extension is instead changed to ".sent" and the queue file is not deleted.

queue Method

Queues the message into QueueDir .

Syntax

def queue(queue_dir: str) -> str: ...

Remarks

This method queues the message into QueueDir. The message is queued into a unique file into the directory QueueDir for future processing.

QueueDir must already exist, or an error will be generated. Alternatively, QueueDir may be set to "*" to return the result as a string instead of writing it to a file.

The method returns the name of the unique queue file created in QueueDir. The file extension is ".queued".

Please refer to the process_queue method for more information on email queue processing.

reset_headers Method

Resets all the message headers to empty.

Syntax

def reset_headers() -> None: ...

Remarks

This method resets all the message headers to "" (empty string). Use this method before creating a new message, so that headers from the previous message are not carried over to the next one.

send Method

This sends the current message and the MIME-encoded attachment.

Syntax

def send() -> None: ...

Remarks

This method sends the current message and the MIME-encoded attachment. If the class is not connected to the mail relay, a connection is created, the message is sent, and then the connection is closed unless an error occurs.

If the class is already connected (by use of the connect method), the connection will remain open after the message is sent. To disconnect, call the disconnect method.

sign Method

Signs the message.

Syntax

def sign() -> None: ...

Remarks

This method signs the specified message.

The message is signed with the private key specified in the Key* properties.

When signing, the following properties may be used to further configure the class:

• ClearSignature
• signing_algorithm

sign_and_encrypt Method

Signs and encrypts the current message.

Syntax

def sign_and_encrypt() -> None: ...

Remarks

This method signs and encrypts the specified message.

The message is encrypted with the public keys specified in the RecipientKey* properties and signed with the private key specified in the Key* properties.

When encrypting, the following properties may be used to further configure the class:

• compression_method
• encrypting_algorithm

When signing, the following properties may be used to further configure the class:

• ClearSignature
• signing_algorithm

@on_key_passphrase.setter
def on_key_passphrase(event_hook: Callable[[PFileMailerKeyPassphraseEventParams], None]) -> None: ...

Remarks

This event fires when the passphrase for the key is required. The passphrase must be specified before operations requiring the secret key are attempted. The passphrase may be supplied by setting the Passphrase parameter in this event, or by specifying the key_passphrase property before attempting the operation.

The passphrase is required when using the following methods in KeyMgr:

• add_user_id
• sign_user_id
• change_expiration_date
• change_passphrase

When using the OpenPGP class, or an email-based class, the following methods require a passphrase for the key:

• decrypt
