Good point. Scanning is a privacy breach that likely
violates privacy legislation. All the more reason to
disable the feature and do your own scanning
*lol*
we have days where 500000 mails for a few hundret users are rejected
straight ahead by postscreen-scoring on the MTA long before
content-filters become a topic
have fun receive that all, scan it local and what about false positives
you overlook - on our MX servers *any* message above 8.0 socre points is
rejected unconditionally, so a sane sender generates *it's own bounce*
to his enduser and nothing is silently dropped
between 5.5 and 7.9 points it get tagged *but not* moved somwehere, just
a SA header and a mark in the subject - the user is responsible at it#s
own how to handle such mails by headers and/or subject
8-10% of all mails not rejected straight away because bad reputation
based ona mix of 50 combined dnsbl/ndswl are rejcted by milter
have fun doing that local where you *must not* reject and backscatter
