I've been running a mail gateway with Postfix, Amavisd-new, ClamAV, and SpamAssassin for about 3 months now running 5.2.1-RELEASE. The server is a dual-AthlonMP 2200+ with 3.5 GB RAM and 3 200 GB drives in a RAID5 setup using a 3Ware Escalade 7506-4LP card. Had some problems with a test install of Courier-IMAP on that server when running the ULE schedule and ADAPTIVE_MUTEXES enabled in the kernel. Trying to manipulate a folder with more than 10,000 messages would panic the kernel (spinlock held for more than 5 seconds, or no kernel memory left) and force a manual run of fsck on the 300 GB /home partition. Switching back to the 4BSD scheduler without ADAPTIVE_MUTEXES fixed that. The server has been running without problems for over a month now. The server blocks about 5,000 spam and 4 - 6,000 virus messages a day, and lets through about 10,000 or so clean messages. Handles mail for about 15 domains. Load average rarely goes about 2, CPU sits around 10 - 15% most of the time. Works quite nicely. -- Freddie Cash, CCNT CCLP Helpdesk / Network Support Tech School District 73 (250) 377-HELP [377-4357] fcash@sd73.bc.ca helpdesk@sd73.bc.ca
