It is possible to turn scanning on based on a recipient using the
"acl_c?" variables to set a flag in the acl_smtp_rcpt, which the
acl_smtp_data will check to see if scanning is required.

Only snag is that if one recipient has scanning enabled, it's enabled
for all. I worked around this by adding a header which can later be
used in routers, transports, and filters. Not the most elegant of
solutions, but it works.
