E-mail protocols [edit]. The Internet Message Access Protocol is an Application Layer Internet protocol that allows an e-mail client to access e-mail on a remote mail server. The current version, IMAP version 4 revision 1 (IMAP4rev1), is defined by RFC 3501. An IMAP server typically listens on well-known port 143.
The authentication protocol itself is a fixed series of messages sent in a specific order. With EAP, the specific authentication mechanism is not chosen during the link establishment phase. Instead, each PPP peer negotiates to perform EAP during the connection authentication phase.
