Hello everyone,

I have a question about spam and the ways that the server blocks these
mail messages. I have a setup where "ServerA" scans mail then delivers
to "ServerB" where it is delivered to local recipients. A few days ago,
we started to experience a rise in spam and virus mail going to everyone
and people wanted to block it. I implemented the regexp_header check to
send for the virus tag and reject the mail if it sees that tag
indicating virus mail.

A few users (3) have indicated to me that they want to now receive virus
email because they are afraid of false-positives. How would I implement
a "spam lovers" map? I only want the map to contain users who ask to
have all spam forwarded.

Thanks,
Anna
