The IMAP Server component is used for receiving mail, managing messages and IMAP folders on the server.
This component represents fully functional multithreaded server with the ability to customize the user and thread performance settings, supports all IMAP4 extensions according to RFC 1730, RFC 1731 and RFC 2060 protocols.
IMAP Server supports multiple mailboxes (IMAP folders) in one user account. User can create, subscribe, unsubscribe, delete and rename folder and append, read, copy, move and delete messages with IMAP4 service.
Working together with POP3 Server allows sharing the "INBOX" folder between POP3 and IMAP servers and read incoming messages with POP3 and IMAP clients simultaneously.
You can use X.509 certificates for establishing the SSL / TLS secured connection.
See SSL / TLS support and Using certificates
With IMAP Server component you can enable debug log for showing entered commands and replies sent to the user.
Please see the Demos code (ImapServer, ImapServerSSL) and also the indexed Help documentation provided with the Clever Internet Suite installation for more details about using this component.
