Remarks

The SSMTP Class is the S/MIME enabled equivalent of the IPWorks SMTP Class. In addition to standard SMTP functions, the SSMTP class can sign and/or encrypt messages in a PKCS envelope. The methods and properties for encrypting and signing are identical to those provided with the S/MIME Class. After setting the certificate properties, and specifying MessageText, call the Encrypt, Sign, or SignAndEncrypt method before sending, and the result will be stored in MessageText.

The SSMTP Class implements a standard SMTP client as specified in RFC 821. It has a simple plug-and-play interface. It contains a number of properties, such as SendTo, Subject, From, Cc, and BCc, that map directly to the internet mail message headers with the same name (RFC 822). The message text is set in MessageText. Messages are sent by calling the Send method.

The class supports message delivery to multiple recipients through the SendTo, Cc, and BCc properties. Simply specify the destination email addresses separated by commas.

The interface of the class is open-ended. New features, including MIME attachments, can be supported by using the OtherHeaders property.

A number of events provide feedback during the operation of the class. The Transfer event is fired during message delivery to show the number of bytes delivered. The PITrail event traces the commands that are sent to the server and the respective replies.

AllowExtensions Property (IPWorksSMIME_SSMTP Class)

This property is a switch allowing the class to use ESMTP features (Extended SMTP).

Object Oriented Interface

public function getAllowExtensions();
public function setAllowExtensions($value);

Procedural Interface

ipworkssmime_ssmtp_get($res, 1 );
ipworkssmime_ssmtp_set($res, 1, $value );

Default Value

true

Remarks

This property is a switch allowing the class to use ESMTP features (Extended SMTP). If this property is True, the class will first send the EHLO greeting (Extended Hello) to the server and, if that fails, the standard HELO command will be sent.

This property is True by default but may be disabled if it is known in advance that the MailServer does not support SMTP extensions.

This property is not available at design time.

Data Type

Boolean

AuthMechanism Property (IPWorksSMIME_SSMTP Class)

This property is used when connecting to the mail server.

Object Oriented Interface

public function getAuthMechanism();
public function setAuthMechanism($value);

Procedural Interface

ipworkssmime_ssmtp_get($res, 2 );
ipworkssmime_ssmtp_set($res, 2, $value );

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.

Data Type

Integer

BCc Property (IPWorksSMIME_SSMTP Class)

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

Object Oriented Interface

public function getBCc();
public function setBCc($value);

Procedural Interface

ipworkssmime_ssmtp_get($res, 3 );
ipworkssmime_ssmtp_set($res, 3, $value );

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 MailServer returns an error code about any email address specified in SendTo or Cc but it will fire an 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 MessageRecipients properties before setting this property to remove previous recipients.

Data Type

String

Cc Property (IPWorksSMIME_SSMTP Class)

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

Object Oriented Interface

public function getCc();

ipworkssmime_ssmtp_set($res, 4, $value );

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 BCc).

The class will return an error if the MailServer returns an error code about any email address specified in SendTo or Cc but it will fire an Error event only if the same thing happens with an email address specified in BCc.

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

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

Default Value

''

Remarks

This 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 multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the class is connected, the LocalHost 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 multihomed hosts (machines with more than one IP interface).

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

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 (e.g., a UNIX host), but it is preferable to select a MailServer that is close to the machine sending mail.

If this property is set to a domain name, a DNS request is initiated. 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.

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

StartTransfer Event (IPWorksSMIME_SSMTP Class)

This event is fired when the message text starts transferring.

Object Oriented Interface

public function fireStartTransfer($param);

Procedural Interface

ipworkssmime_ssmtp_register_callback($res, 8, array($this, 'fireStartTransfer'));

Parameter List

 'direction'

Remarks

If MessageText is not empty, the StartTransfer event is fired when the MessageText starts transferring from the local host to the MailServer. If MessageText is empty, the event is not fired.

If a file is attached to the MessageText via the AttachedFile property, then StartTransfer fires again when the file starts transferring. Please go to the description of the AttachedFile property for more information.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Transfer Event (IPWorksSMIME_SSMTP Class)

This event is fired when the message text is transferred to MailServer .

Object Oriented Interface

public function fireTransfer($param);

Procedural Interface

ipworkssmime_ssmtp_register_callback($res, 9, array($this, 'fireTransfer'));

Parameter List

 'direction'
 'bytestransferred'
 'percentdone'
 'text'

Remarks

One or more Transfer events are fired during message delivery. Messages consist of MessageText and an optional AttachedFile. The BytesTransferred parameter shows the number of bytes sent starting from the beginning of MessageText or AttachedFile.

Text contains the current portion of the message being sent.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
