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. > I am going to add some more memory for general principle to keep it > from having to kick into the swap file. 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. > Once administration likes > what it is doing, I will probably be given the money to put it on a > system with more processor and memory. 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. -kgd -- Get your mouse off of there! You don't know where that email has been!
