This package provides a remote mail retrieval and forwarding utility intended for use over
on-demand TCP/IP links, like SLIP or PPP connections. Fetchmail supports every remote-mail
protocol currently in use on the Internet (POP2, POP3, RPOP, APOP, KPOP, all IMAPs, ESMTP
ETRN, IPv6, and IPSEC) for retrieval. Then Fetchmail forwards the mail through SMTP so you
can read it through your favorite mail client.
If you need to retrieve mail via SLIP or PPP connections, install fetchmail.
