We're running FreeBSD 5.2.1 (soon 5.4) with Postfix 2.1, Amavisd-new 2.x, SpamAssassin 3.x, and ClamAV 0.83 (soon 0.84), on a dual-AthlonMP 2200+ with 4 GB RAM and 400 GB diskspace on a RAID5 array (3Ware Escalade 7604-LP). This is all stored in a 2U rackmount server. This is not a name-brand server, but comes with local warranty and support. This is the filtering mail gateway for a school district, and handles 15-20 domains, roughly 30,000 mail accounts (students and staff), ~20 mailing lists, and filters both incoming and outgoing messages. This is the primary MX for all the domains, and delivers mail to the appropriate mail servers for message storage and retrieval. School firewalls also intercept all outgoing SMTP connections and forward the messages to this server, so all outgoing mail is scanned, regardless of what SMTP server is configured in the users' mail program. This server processes approximately 250,000 messages per month, with about 56% blocked as spam, and 15-20% blocked due to viruses. If needed, I can post the mail stats for Sept. 2004 (when the server went online) to Apr. 2005. This box is very lightly loaded, and was even used as a test Courier-IMAP and Cyrus IMAP server for the IT department (15 accounts) without any issues. Now it's just the filter server. -- Freddie Cash, CCNT CCLP Helpdesk / Network Support Tech.
