yes. there are a lot of pix firewalls out there with smtp fixup turned on,
effectively disabling ESMTP (not to mention sporadically breaking
traditional SMTP.)
Could you elaborate on this? I use PIX firewalls all over the place and
don't seem to have a problem with SMTP or ESMTP.

problem when an SMTP server is hosted behind the PIX? I
thought the fixup statements were for outbound connections, and with it on
right now I get the full banner from SMTP servers. I don't host an SMTP
server myself, so can't check that.

e gets slashdotted on the 30th. The difference is in 29 days of
downtime. And no, I don't have a solution to offer for that one, but that's
what always annoys me - to see a site get slashdotted at the beginning of
the month, knowing my attention span won't last until next month :)

doing Windows Update on the day of install and never having a firewall...

I damn well ain't sharing that with
anyone. In the meantime, the ISP noticed the virus and put a block on.
Do I have to pay them $500 to get it removed? Definitely cheaper to cancel
service and go with someone else at that point.

Eventually all the "bad" customers end up with the same ISP, then
filtering is as easy as running loose uRPF and filtering on their AS on input.
And that's why we can all safely dump anything from aol.com into /dev/null,
right? ;)

say, the "ping" service of your core router to the MRTG charts of bandwidth

There are similar boxes from FatPipe and Radware (and others) that
promise the same thing. I've done some light research on them and while
I can see some positives, I don't prefer them to our current solution.
Then again, I don't have any practical experience with them and I hope
someone who has

way-more-efficient 1U colo model.
On the other hand, if the person doesn't have a UPS at home, what good is
when their SMTP server in a colo is still chugging? :)

Any thoughts? Have NANOG powerpoint presentations made these sorts of
