remote-mail protocol now in use on the Internet: POP2, POP3, RPOP, APOP,
KPOP, all flavors of IMAP, ETRN, and ODMR.  It can even support IPv6
and IPSEC.

Fetchmail retrieves mail from remote mail servers and forwards it via SMTP,
so it can then be read by normal mail user agents such as mutt, elm
or BSD Mail.  It allows all your system MTA's filtering, forwarding, and
aliasing facilities to work just as they would on normal mail.")
