First the .forward file didn't work.
After using tail /var/log/mail.log I discovered this:
Sep 19 23:26:53 localhost sendmail: g8K4Qri4000669: from=sean, size=44, class=0, nrcpts=1, msgid=<200209200426.g8K4Qri4000669@localhost>, relay=sean@localhost
Sep 19 23:26:53 localhost sendmail: g8K4Qri4000669: to=root, ctladdr=sean (501/20), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30024, relay=localhost [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by localhost
It seems for some reason sendmail is being refused.
Then there's the problem with killing my privliges on the root directory (/). How do I get them back since sudo chmod g+w / doesn't work?
