We've been under a constant bounce bombardment of bounced
spams (from f*cking idiot admins who can't understand that
you do not bounce after accepting, sorry for the language)
where the majority of user names are
[EMAIL PROTECTED] (where roger is any valid name).
We had one advance MX server that usually ran 32 connections
out of 120 and now we've had to bring on 3 additional servers
all running 300 connections and we've had to turn off SA
processing because the incoming load is just too high.
I'd really like to take a bat to the knees of the spammer
doing this AND the mail admins who bounce after accepting.
Just my $0.02
Don't get too mad, but I'm one of those "f*cking idiot" admins who is
bouncing after acceptance. The reason isn't (just) because I'm a "f*cking
idiot" admin, but because I use "f*cking idiot" software that Management
hasn't seen fit to upgrade yet, probably because I'm doing such a good job
keeping it running :-)
What it comes down to is that I have a Linux machine at the front-end,
running MimeDefang, Spamassassin, etc., which passes everything it hasn't
rejected on to an old Exchange Server. I can't turn off the bounce messages
at the Exchange Server (for various stupid reasons that only Bill Gates
could explain), but I have no way of rejecting mail at the Linux machine,
because I don't know which addresses are valid.
I'm still working on a way to do this - I'm sure it's not impossible, but I
haven't had much success yet. Ideally, the Linux machine would do an LDAP
query to the Exchange server, but unless you can help me figure out how to
do it, then I guess I'll just remain a "f*cking idiot admin".

You aren't "f*cking idiot admin" but you should get yourself manually
listed in an RBL such as spamcop or something so we don't have to see
the bounces from your incoming MX server (I assume that outgoing mail
comes from your exchange server and not from your Linux front end).
Hey, if you are running qmail, add a default smtproute in smtproutes
mydomain.org:exchangeserver.mydomain.org
:127.0.0.1
That way your mail gets delivered and the bounces get routed back to
localhost and doublebouce, and then you can set doublebounceto to # in
qmail.
Voila, no more bounce backs!
Amazing!
I'm sure you can do the same thing in Postfix, sendmail or what ever
mail MTA you are using.
There are easy solutions to all problems, you just have to look at the
problem correctly.
Sorry, sarcasm is high tonight and I've had a few beers on about 8 hours
sleep in the last 72 hours. No offense meant, but the above will fix
the bounce backs.
