I am running Antigen for Exchange on a Exchange 2003 machine. My Outbound
Mail Queue constantly has messages from my Postmaster that are in RETRY state
trying to send NDRs (I guess) to what I assume are "spoofing" spammers. For
these, the Additional Queue Information shows "the remote server did not
respond to the communication request" which indicates the spam came from a
spoofed or illegitimate source, right?
I have added many of these spoofing spammers, the domains and or IPs, to my
Rejected Mailhost lists but I continue to see my Postmaster is trying to send
NDRs to the same blocked Rejected Mailhost.
It seems like if you block a domain\mailhost that your server would never
try to send a NDR reply to the illegitimate source. Does that all makes sense?
Any ideas are much appreciated...
