That's overkill, and then some. :) I don't have direct experience with Dell servers (we're actively replacing those with white-box systems), but me experience with a mail gateways follows: We're running a dual-AthlonMP 2600+ (1.8 GHz) system with 3.5 GB DDR RAM, and 3x200 GB WD IDE drives in RAID 5 acting as mail gateway. Software includes FreeBSD 5.2.1-p8, Postfix, Amavisd-new, SpamAssassin, and ClamAV. This server handles virus / spam filtering for 15 domains, and about 25,000 unique mail accounts (15,000 staff, 10,000 students, give or take a bit). We get a hell of a lot of messages per day (although I haven't tracked the exact number or trends yet, but could extrapolate around the 50,000 mark), and I've yet to see the server CPU load get above 5 - 10 % and the system load rarely goes above 2.0. The mail queue rarely gets above 200 messages, and most of those are bounce messages to non-existent or uncooperative servers. (This server is also being used to test Courier-IMAP and Cyrus-IMAP with SquirrelMail, so there's the odd spike during testing, but everyday use never taxes the system). We're actually planning on replacing this with a non-RAID system with a single AthlonXP or Athlon64 so we can use this server as part of the back-end of the new mail system coming in next month. -- Freddie Cash, CCNT CCLP Helpdesk / Network Support Tech.
