Install Postfix

# emerge postfix -va

Configuration

edit /etc/postfix/main.cf

myhostname = zero.iat.sfu.ca 
           naturally, use your server's real name :-)

mydomain = iat.sfu.ca

add to /etc/postfix/main.cf

# rewrites addresses
sender_canonical_maps    = hash:/etc/postfix/sender_canonical

We don't receive mail, so comment this line out, as shown, in /etc/postfix/main.cf

#mydestination = $myhostname, localhost.$mydomain, localhost


Check that these are uncommented, in /etc/postfix/main.cf. Gentoo is shown; other distributions omit the /mail path.

alias_maps = hash:/etc/mail/aliases
alias_database = hash:/etc/mail/aliases

Create the file /etc/postfix/sender_canonical. This ensures that any replies or whatever will go to a real (or nearly :-) ) human

root     gordonp+server_name@sfu.ca

Create the .forward file in root's home-dir. This will cause root-directed mail (like logwatch and cron output) to go to our admin mailing-list:

admin@siat.sfu.ca
