I've got an even better example if not as well publicized. When SoBig
first hit my address was one that was being spoofed. I had tracked it to
RoadRunner (rr.com). I forwarded them an example piece to tell the guy to cut
it out. I was not yet aware of SoBig. Anyway they rejected at SMTP because
I am in DSLExtreme's residential block. Fine, I'll call. I get the number
for abuse from the whois database. I get a recording that tells me under no
uncertain terms will they accept phone calls and I must email them directly.
I call into the corporate headquarters and complain to a CCR. He tells me he
cannot forward my call but is willing to walk over and talk to them directly
if I provide him with the appropriate information.
After fuming and learning what SoBig was I just let it drop. A friend
asked if they had postmaster blocked as well. They did. I just found it
mildly amusing that I, someone who's ran an SMTP server in residential space
(with blessing from my ISP) for over two years now without a single complaint,
was prevented from complaining about one of *THIER* residential customers who
couldn't figure out he was spewing 100k attachments as fast as his little
cable router could chug them out. End result: I blacklisted him at the
firewall, had my secondary do the same. *shrug*

Hell, it has two different methods of doing it. Exiscan-ACL and SA-Exim.
Exiscan-ACL was just recently added to exim4-daemon-heavy so for all intents
and purposes anyone running Exim4 on a dedicated host already has the
capability for SA filtering at SMTP.
