    I'm using greylisting and spam assassin with razor2 pyzor dcc and am very happy with the results.

    here's my complaint: I see in my report that one domain in particular with only one user is getting 4000 or more per day "Reject Recipient Address"

    This is tying up bandwidth and needlessly using up server resources. The IP addresses seem pretty varied. Probably infected machines spewing this garbage out.

    Has anyone dealt with this successfully? I'm ready to get this user off my server even though they are just a victim too.

    I guess that some spammer is abusing that user's email address as the sender address for his spam. That's not the user's fault, but explains why he's getting all those "Reject Recipient Address" messages.

    i'm not sure, but maybe greylisting helps against these bots...
