This component is part of the IP Works Enterprise ASP.NET Component Library.

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

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks
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 via the component's methods. The main arguments for most commands is the Mailbox property or 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 SearchCriteria, MessageFlags, etc.

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

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.

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.
