fetchmail is a full-featured
IMAP and POP client which
allows users to automatically download mail from remote
IMAP and POP servers and
save it into local mailboxes; there it can be accessed more easily.
fetchmail can be installed using the
mail/fetchmail
port, and
offers various features, some of which include:
Support of POP3, APOP, KPOP, IMAP, ETRN and ODMR protocols.
Ability to forward mail using SMTP, which allows filtering, forwarding, and aliasing to function normally.
May be run in daemon mode to check periodically for new messages.
Can retrieve multiple mailboxes and forward them based on configuration, to different local users.
While it is outside the scope of this document to explain
all of fetchmail's features, some
basic features will be explained. The
fetchmail utility requires a
configuration file known as .fetchmailrc
,
in order to run correctly. This file includes server information
as well as login credentials. Due to the sensitive nature of the
contents of this file, it is advisable to make it readable only by the owner,
with the following command:
%
chmod 600 .fetchmailrc
The following .fetchmailrc
serves as an
example for downloading a single user mailbox using
POP. It tells
fetchmail to connect to example.com
using a username of
joesoap
and a password of
XXX
. This example assumes that the user
joesoap
is also a user on the local
system.
The next example connects to multiple POP and IMAP servers and redirects to different local usernames where applicable:
The fetchmail utility can be run in daemon
mode by running it with the -d
flag, followed
by the interval (in seconds) that
fetchmail should poll servers listed
in the .fetchmailrc
file. The following
example would cause fetchmail to poll
every 600 seconds:
%
fetchmail -d 600
