We're about to do the same, but since mail is delivered to another
machine with SMTP (or eventually with LMTP with a transport that looks
roughly the same) we have "no loop". Don't know if this is usefull, but
this is my transport:

scan_smtp:
driver = smtp
# would use batch_max = 1 here with pipe or lmtp
max_rcpt = 1
serialize_hosts = *
transport_filter = /usr/local/bin/spamc -u $local_part
size_addition = -1
rcpt_include_affixes = true

In my test-setup this seems to work nicely with per-user preferences
stored in SQL,
(if anyone sees a downside to this approach instead of the pipe (unless
for that being usable in more situations)...)
