Someone tried to hit the mailman-users list like this, and forged my own
e-mail address to do it. Fortunately, they got caught by our anti-spam
filters and rejected, and I only found out because the bounce message
was not deliverable. Oy.
I have complained to the ISP in question, but the problem is that
replies to that message are going to run afoul of the same anti-spam
filter, so I'm probably not going to see them. I'm in the process of
trying alternative methods of contact.
Fortunately for me, I happen to know the guy who runs the Internet
Security group at this large broadband ISP (he's a former co-worker of
mine from my AOL days), and he is the primary reason why I consider this
to be one of the best large ISPs around.
Yes, I am going to be tightening the security on this list.
