Whitelisting for (avoiding) virus scans is hard
to defend, but one doesn't have to whitelist
for virus scan to whitelist for spam scans.

For instance, with trusted users it is reasonable
to whitelist (bypass) SpamAssassin for all
authenticated users but still virus scan those
messages.

Sure, but using the new *list_from_rcvd (SA 3.10)
can be very effective to white/black list
and avoid forgeries by using not only the
name but the received from server.
