IMAP Component

Properties   Methods   Events   Config Settings   Errors  

The IMAP Component is used to communicate with IMAP servers using the Internet Message Access Protocol (IMAP).

Syntax

nsoftware.IPWorksSSL.IMAP

Remarks

The IMAP Component supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections (RFC 2595). When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method.

The IMAP Component implements a standard IMAP client as specified in RFC 1730 and RFC 2060.

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.

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 show the flags pertaining to the mailbox.

A number of operations may be performed by the server in response to commands sent using 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 and MessageFlags.

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

The MessagePart event describes the MIME structure of the 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 RetrieveMessagePart method. This speeds up processing by avoiding the need to retrieve full messages from the server.

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.

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 component initiate connections (or accept in the case of server components) 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 component 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).

  Public ReadOnly Property CertSubject As String
  Public ReadOnly Property CertIssuer As String
  Public ReadOnly Property Status As String
  Public Property Accept As Boolean
End Class

Remarks

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.

SSLStatus Event (IMAP Component)

Fired when secure connection progress messages are available.

Syntax

• C#
• VB.NET

public class IMAPStartTransferEventArgs : EventArgs {
  public int Direction { get; }
}

Public Event OnStartTransfer As OnStartTransferHandler

Public Delegate Sub OnStartTransferHandler(sender As Object, e As IMAPStartTransferEventArgs)

Public Class IMAPStartTransferEventArgs Inherits EventArgs
  Public ReadOnly Property Direction As Integer
End Class

Remarks

The StartTransfer event is fired when the message body or the part data start transferring from the server to the local host. Further progress information is provided by the Transfer and EndTransfer events.

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

Transfer Event (IMAP Component)

This event is fired while the message is transferred from the MailServer .

Syntax

• C#
• VB.NET

public event OnTransferHandler OnTransfer;

public delegate void OnTransferHandler(object sender, IMAPTransferEventArgs e);

public class IMAPTransferEventArgs : EventArgs {
  public int Direction { get; }
  public long BytesTransferred { get; }
  public int PercentDone { get; }
  public string Text { get; }
}

Public Event OnTransfer As OnTransferHandler

Public Delegate Sub OnTransferHandler(sender As Object, e As IMAPTransferEventArgs)

Public Class IMAPTransferEventArgs Inherits EventArgs
  Public ReadOnly Property Direction As Integer
  Public ReadOnly Property BytesTransferred As Long
  Public ReadOnly Property PercentDone As Integer
  Public ReadOnly Property Text As String
End Class

Remarks

The Transfer event is fired for every incoming line when receiving a message or part data from the MailServer

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.
