SMTP Auth...sendmail not using

60s TV Batman · 07-17-2008, 04:16 PM

I've been trying to get SMTP Auth up and running on one of my web servers (running Fedora 7).

For some reason, Sendmail isn't activating STARTTLS, and I don't know why.

The command "service --status-all" shows dovecot, sendmail and saslauthd are all running...

dovecot (pid 7249) is running...
saslauthd (pid 9309 9308 9307 9306 9304) is running...
sendmail (pid 9735 9727) is running...

I'm not very clued up on SMTP Auth, but need to provide remote users with a way to log in their email from Outlook Express and similar. I can do this by putting their IP address in access.db, but of course that doesn't work if they're not at their regular computer or don't have a fixed IP address.

SMTP Auth would seem to be the answer, but I can't get it to work.

I think I need some expert help to get this working. Anybody willing to help me out here?

Here's output from the log of a failed send attempt from my own PC via the webserver in question:

Something has gone very wrong with sendmail on my server. Sendmail won't relay any messages through it, even though I have my original (previously working) access.db back in place.

I can receive email to, but not send.

I'm all out of ideas. Is there anyway to simply reset sendmail to it's out of the box configuration and start again?

NOTE: I saved my original sendmail.mc, but restoring this and rebuilding sendmail.cf makes no difference.
