your best option is to use amavisd-new, which has all the necessary
functionality and more.
otherwise, if you are calling SA from a script, and then using the
sendmail command to resubmit mail after filtering, then you can
- add an smtpd listener, say on port 10125 as well as an associated
leanup service
- configure this cleanup service to use specific header_checks
- in these header checks, use something like:
/^X-Spam-Status: No, score=\d{2}/ HOLD
HOLD will put the mail on hold, and you can then review it, discard it,
inspect it, ... using postcat and postsuper.
PS. you could use DISCARD if you feel confident. if so, remember: it's
your mail, not mine. if you lose mail, I won't even feel sorry I could,
but I would be a liar) ;-p

with amavisd-new, you would have a daemon doing spamassassin (without
forking a spamc process) and doing more (configurable delivery options,
... etc).
