Post Office Protocol

messaging, protocol (POP) A protocol designed to allow

single user computers to retrieve electronic mail from a POP

server. The POP server might be a computer with a permanent

Internet connection whereas its clients might only connect

to it occasionally, e.g. by modem.

There are (in 1994) three versions: POP, POP2, and POP3.

Later versions are NOT compatible with earlier ones.
