Hi, as I mentioned to Tom in reply to his message - yes you are correct,
the bounces are not fake as they appear to be coming from valid AOL IP
address/servers. But their origin is suspect - and given that our user
is getting 30+ a day with different (obvious virus) attachments then we
have to consider that they are getting into AOL somehow and being pushed
to our server. His machine has been virus checked plus he is behind
corporate firewall which blocks port 25 from him. So I don't think they
are bounces from him sending out viruses to AOL accounts.

However even if that was the case, we get back to my initial question -
how can we block these messages?

The exim log shows..
