Sadly, it is/was coming from my machine. :<
I've upgraded the server and blocked about 8 class A networks at my
firewall. It's draconian, but it seems to have stemmed the tide until I
can look at the problem tomorrow (it's 2:30am now...).
It looks like they've found a way to connect to my machine's sendmail
even though relaying should be denied. Any idea how this could have
happened? At any rate, I will look into that tomorrow. Thanks for your help!
