major electronic mail protocols?

[Westat1]

What are major electronic mail protocols and where can I find out "free" information on them?

[BlobFisk]

SMTP (Simple Mail Transfer Protocol), POP (Point Of Presence), IMAP (Internet Message Access Protocol), MIME (Multipurpose Internet Mail Extensions) and ACAP (Application Configuration Access Protocol) are the big ones - TCP/IP (Transmission Control Protocol and Internet Protocol) are also used for the transmission IIRC.

A Google search on these should yield some good resource sites.

POP is the Post Office Protocol.

The term is also used by ISPs to signify the presense of a modem pool for subscribers, hence Point Of Presense, but it is not related to mail.
