USING A POP CLIENT
Most popular Mail User Agents today, such as mozilla, mutt, evolution, are POP aware, and
can be used as POP clients.
There is also a popular command-line POP client called "fetchmail". fetchmail is highly
configurable, can query multiple mailboxes, and can run in daemon mode, such that it could query a
user's mailbox every five minutes.
fetchmail delivers the mail pasing it off to the MTA an a localhost, usually "sendmail".
vi ~user/.fetchmailrc
poll stationX.example.com with protocol pop3:
user user there is user user here
password "redhat"
The passwords are stored in this file, fetchmail will refuse to run unless you make the file readable
only by owner
chmod 600 ~user/.fetchmailrc
chown user ~user/.fetchmailrc
Attempt to "pop" your mail as user.
echo " testing" | mail -s "hi" user
su - user
fetchmail -v
logout
Now fetchmail is able to fetch mails from other hosts.
