I am using it as a passthru to my two on campus mail servers that have the mail accounts for staff/faculty/students. That is one of the reasons that I picked the Scott Henderson guide to build my system around so I wouldn't have to migrate all the accounts to it. I am going to add some more memory for general principle to keep it from having to kick into the swap file. 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.

A P2/400 won't break a sweat just doing SMTP and POP3 service for thousands of accounts; doing content filtering such as SA on the same number of accounts pushes your processing requirements up by something not far short of an order of magnitude. I've got a P3/866/512M system with ~300 accounts, processing ~100K messages/week- and while it's still got some headroom, it occasionally bogs down if there's a spike in traffic. It had been a P2/450, which was OK if the previous system in the relay chain (don't ask) kept a fairly steady serialized stream of mail coming... but if the flow increased even a little, processing bogged down and mail backed up. On the conservative side, say each user receives 20 pieces of mail each week. That's 30K messages per week. But those accounts are going to start seeing spam, on the order of a minimum of ~10 spams/day, after a few months. That's another 70 messages/week/account - 105K messages. And that's a *very* low spam volume. Many accounts will probably see 50-100 spams daily within about 6 months - ~1M messages/week. Quite a few will probably see up to 200/day. And a few will probably manage to sign up for enough dodgy mailing lists to get their address far enough out to see 300+ spams/day. :P Ugh. For spamfiltering 1500 accounts, on a single box, I wouldn't go with anything less than a dual P3/800/512M; given memory prices these days I'd probably push that up to a gig. A fast disk system is also helpful. -kgd -- Get your mouse off of there! You don't know where that email has been!
