The PIMAP component is used to communicate with IMAP servers to retrieve and process OpenPGP encrypted and/or signed messages and any attachments.

Syntax

TipgPIMAP

Remarks

The PIMAP component offers an easy-to-use interface: it implements a standard IMAP client, as specified in RFC 1730 and RFC 2060, and supports decrypting and verifying signatures of encrypted and signed emails using OpenPGP. 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 to use.

Connect to a Mail Server

The first step in using the component is specifying a MailServer, a User to connect as, and a Password to authenticate with. After that, one or more requests may be sent to the server via the component's methods. Results are retrieved through events and a number of key properties.

Examine a Mailbox

Normally, after connecting to the server a Mailbox is selected (or examined) using the ExamineMailbox method. After the Mailbox is selected, MessageCount and RecentMessageCount show the number of messages in the mailbox, and MailboxFlags shows the flags pertaining to the mailbox.

A number of operations may be performed by the server in response to commands sent via the component's methods. The primary arguments for most commands are the Mailbox property and the MessageSet property. The MessageSet property denotes either a single message or a range of messages. Other arguments are specified through other properties such as SortCriteria, MessageFlags, etc.

Responses are received through events such as MessageInfo and MailboxList, and are also reflected in properties such as MessageText, MessageSubject, etc.

Decrypt

To process an encrypted or signed message, first retrieve the message text and headers by calling FetchMessageHeaders and FetchMessageText. To decrypt a message specify the private key to be used for decryption by setting the Key* properties. For instance: PIMAP1.KeyCount = 1 PIMAP1.KeyKeyring(0) = "c:\my_keyring_dir" PIMAP1.KeyUserId(0) = "recipient@nsoftware.com" PIMAP1.KeyPassphrase(0) = "password" The specified private key will be used to decrypt the message when calling Decrypt.

Verify

To verify the signature of a message specify the public key to be used for signature verification by setting the SignerKey* properties. For instance: PIMAP1.SignerKeyCount = 1 PIMAP1.SignerKeyKeyring(0) = "c:\my_keyring_dir" PIMAP1.SignerKeyUserId(0) = "sender@nsoftware.com" The specified public key will be used to verify the signature when calling VerifySignature. To decrypt and verify in one step call DecryptAndVerifySignature.

Retrieve MIME Message Parts

The MessagePart event describes the MIME structure of retrieved messages. One MessagePart event is fired for every message part, giving information about the particular part. Later on, message parts may be retrieved separately through the FetchMessagePart method. This speeds up processing by avoiding the need to retrieve full messages from the server.

Trace Client and Server Communication

The PITrail event traces the interaction between the client and the server. It includes all exchanges except for transfers of messages, message parts, and message headers.

Timeout Property (PIMAP Component)

A timeout for the component.

Syntax

__property int Timeout = { read=FTimeout, write=FSetTimeout };

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 component will wait for the operation to complete before returning control.

The component will use DoEvents 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 component raises an exception.

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.

This method removes all messages marked with a 'Deleted' flag from the currently selected mailbox and closes the unselected mailbox.

Syntax

void __fastcall CloseMailbox();

Remarks

This method permanently removes all messages that have a 'Deleted' flag that have been set from the current (selected) mailbox. It then closes (deselected) the mailbox.

Config Method (PIMAP Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

This method may be used when the data is signed, encrypted, or signed and encrypted. For instance, if the data is encrypted but not signed you may still use this method and the component will perform the decryption without error.

The message will be decrypted using the keys specified in the Key* properties. Before decryption begins the component will fire the RecipientInfo event with information about the encrypted message, including the key used to encrypt the message. Within this event you may use the available information to load the correct key into Keys.

The message will be verified using the keys specified in the SignerKey* properties. Before verification begins the component will fire the SignatureInfo event with information about the signature including the key used to sign the message. Within this event you may use the information available to load the correct key into the SignerKey* properties.

By default, if the signature is not valid the component raises an exception. The configuration setting RequireValidSignature may be set to False to disable this requirement.

The Text parameter contains the portion of the message or the part data being retrieved.

The BytesTransferred parameter contains the number of bytes transferred since the beginning of the message, including header bytes. At the end of transmission (i.e., when the last Transfer event is fired), BytesTransferred equals the value of the MessageSize property.

The Transfer event is fired for every line of the message. There is no terminating newline at the end of the Text parameter. A faster way to retrieve a message is to assign a value to the LocalFile property and use the Transfer event to check the progress only rather than to get the actual data.

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.

VerificationStatus Event (PIMAP Component)

Fired after verification of the signed message.

Syntax

typedef struct {
  String KeyId;
  int Status;
} TipgPIMAPVerificationStatusEventParams;
typedef void __fastcall (__closure *TipgPIMAPVerificationStatusEvent)(System::TObject* Sender, TipgPIMAPVerificationStatusEventParams *e);
__property TipgPIMAPVerificationStatusEvent OnVerificationStatus = { read=FOnVerificationStatus, write=FOnVerificationStatus };

Remarks

This event fires when VerifySignature or DecryptAndVerifySignature is called. It provides information about the result.

KeyId is the Id of the key used to sign the message. It is the hex-encoded, 4-or 8-byte Id of the key. It is the same as the last 4 or 8 bytes of the Fingerprint. For instance:

BF52A0AB

Status holds the result of the operation. Possible values are:
