[cobalt-users] spam relaying

["Manny Tau" <mtau@xxxxxxx>]

Ugh, after been working on this throughout the day, my 550 is still been
used as a spam relay.

I've checked with http://www.abuse.net/relay.html and it says "All tests
performed, no relays accepted."

My 550 settings for now:
Pop Authenticated Relaying turned on.
IP Address Allocation turned on with the beginning and end range with my
single IP address.
I made sure that my /etc/mail/access only has my full IP set for relay, and
not just the first 3 quad numbers.
The 550 is fully patched, including a recent Sun sendmail patch, and after
the Sun patch, installed RaqTweak's newest sendmail patch to address CERT
CA-2003-12, which the latest Sun sendmail patch doesn't address.

But I'm still getting spam relaying activity.

Any suggestions and how to plug this up?

Here's the latest 5 entries from my log...it has different sources in the
'relay=' as opposed to a single culprit, like I had earlier today but
plugged up that hole.
