Please give us some clues at least as to how its configured - the
default configuration does no content based filtering so you cannot be
running with the defaults. As there are several ways of doing content
scanning we can't sensibly comment on how you are currently
misconfigured.
The current standard way of doing content scanning is to use the exiscan
extension (part of the mainstream release since version 4.50, an add-on
patch prior to that version).
With exiscan you will have entries in your data acls something like this
(this is a reacted version of the one running on exim.org):-
acl_check_content:
# do real virus scanning with clamav - reject matches
deny message = This message contains malware ($malware_name)
demime = *
malware = *
# list stuff & authenticated....
accept hosts = +relay_from_hosts
accept authenticated = *
# large messages are CPU intensive to spam scan, so we skip
# them by accepting them here...
accept condition = ${if >{$message_size}{256K}{1}{0}}
# do spam scanning - mark up stuff
# put score header in all messages (no matter if spam or not)
warn message = X-Spam-Score: $spam_score ($spam_bar)
spam = exim:true
# reject spam at high scores (> 8)
deny message = This message looks like spam ($spam_score spam
points).
spam = exim
condition = ${if >{$spam_score_int}{80}{1}{0}}
Now none of this produces bounces to the original sender for either
virus or spam messages. It does however produce a SMTP reject. This
may cause a previous relaying MTA to produce a bounce to the original
sender, but thats not my problem - I have done the right thing and
refused to accept it and indicated my refusal to the system talking to
me.
