The problem is the following. SpamAssassin is bouncing to the reply-to address, which typically has nothing to do with the spamers. The recipient flags your bounce as spam, Barracuda picks that up, and we are blacklisted.
No. Nebka is blacklisted. Nebka has no spam filter. Raneb, snefru, fafner, and khufu, all of which have spam filters, are not blacklisted. Nebka has a problem with just one spamlister, who stupidly thinks that the spam it forwards to the spamfiltered machines, and that gets spamfiltered there and rejected, is itself making nebka suspicious of spamming. That's the way I read this story.
So, just kill the spam, do not bounce.
There is no bounce. It's an smtp runtime error. It's the default behavior of the package. Cheers, Thomas Krichel http://openlib.org/home/krichel RePEc:per:1965-06-05:thomas_krichel phone: +7 383 330 6813 skype: thomaskrichel
