The Post Office Protocol 3 (POP3) and the Internet Message Access Protocol 4 (IMAP4) are standard messaging protocols for the Internet. The GroupWise GWIA can function as a POP3 or an IMAP server, allowing access to the GroupWise domain database and message store. With POP3 or IMAP server functionality enabled, GroupWise users can download their messages from GroupWise to any POP3/IMAP4-compliant Internet email client. To send messages, POP3/IMAP4 clients can identify the GWIA as their SMTP server.
NOTE:Internal IMAP clients can connect directly to the POA, rather than connecting through the GWIA. For more information, see Section 15.2.2, Supporting IMAP Clients. Direct connection provides faster access for internal IMAP clients.
