I'm pissed (was-Fwd: (forw) Undelivered Mail Returned to Sender)

My reply to natbib and apacite is attached.

Once again, my mail to this list is bouncing.  Why?  These absolute morons that 
are running ISP's are now blocking mail from dynamic IP addresses, as if that 
means the sender is a spammer.  So these shit for brains admins who don't 
have the first clue about how to block spam take this approach of blocking 
arbitrary dynamic ip's, and do nothing to protect non-spam messages.  Even 
worse, this list doesn't get spammed to begin with, so they end up blocking more 
legit mail than spam.  If they don't fix their ignorant ways, I won't be participating 
in this mailing list anymore.
