Broken Mail server

[v2k]

Running fedora core 7: Mail has stopped working. Here's the error from the logs:

Apr 1 00:13:18 localdomain sendmail[13388]: m317DIQ1013388: to=myemail@gmail.com, ctladdr=admin (500/500), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30042, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1]

Not sure what I've done. I thought it might have been my hosts.deny not allowing localhost to send mail, but I added
ALL: 127.0.0.1

to hosts.allow

Any thoughts on what to check?

[v2k]

I'd like to say I fixed it... but I'm not sure what I did. postfix was down. I had been unable to restart it -- perhaps because I was not root. I logged in as root, restarted it and it worked. Perhaps it's failing to start on boot up.

I think you have not setup your alternatives properly those were logs from sendmail not postfix.

[v2k]

I thought it was only supposed to work with postfix. If it's supposed to work without it then yes, I've definitely setup something wrong. I thought it was port 25 that might have been the issue, but opening that up made no difference. I have never had sendmail working without postfix running.
