my system rejected them as spam, so they were spam (or so likely to be spam as
makes no difference).
if you can bring yourself to care about the one in a million that might not be
spam, then feel free to do so. i certainly can't and don't....and on my
systems, it's what i care about that counts.

i'm quite capable of configuring spamassassin as a content-filter that runs
during the smtp session rather than after it.
i choose not to, because there is a fairly high risk of SMTP session timeouts
when the system is under heavy load, resulting in a) repeat attempts to deliver
the same mail to my server (wasting more bandwidth and CPU power to scan it),
and b) the small possibility of an undesirable feedback loop of ever-increasing
it's less hassle and less dangerous to just accept it, classify it, tag it if
necessary, and deliver it....the MDA can filter it as appropriate.

i didn't see that. will hunt for the thread.

382 tagged in a week, about half of which go to my SPAM.incoming folder (the
rest go to other users, so don't concern me directly). most are nigerian 419
scams and can be ignored, a handful have extra domains/ip addresses/phrases to
add to my lists.
not exactly what i'd call an excessive or obsessive work-load.
it's not even enough of a workload to bother using procmail rules to drop
extremely high scoring spams into /dev/null

more than the 1.5% of spam that makes it through my postfix filters to be
tagged by SA? i suspect that you do.
