Passthrough or local delivery, content filtering is VERY process- and
memory-intensive.  Your P2/400 WILL choke on 1500 accounts' worth -
*especially* if any significant number of those accounts have been
active for a while and are already getting several hundred spams per
day.

With passthrough filtering such as you're looking at, you *may*
occasionally gain some benefit from messages with multiple recipients
only running through the filter process once...  but that's really not
going to be very many messages.

32M is fine for SMTP and POP3 (barely) with 1500 accounts;  you'll need
at least 256M to do any kind of reasonable filtering, and More Is
Better.  Try putting the mail queue on a ramdisk/tmpfs;  that reduces
the delays due to moving data onto physical disks.

If there's any way you can see to only filter a few specific accounts,
do it as the "show the administration what's possible" test.
