I guess I forgot about the mail server. If you have a loadbalancing set with mysql on two systems, you have the replication issue. I would do: <FE> (main mx record to the world) postfix/DNS/DCC,mysql, 'special' dns entry for postfix/transport should round robbin SA1 and SA2 <SA1> <SA2> <Mail Server> (remember, SA with lots of rules takes the most time, clamav will also) > mx1 and 2 will have amavis/clamd/SA/postfix and will forward > all incoming mail to <Mail Server> and having both mx dns > records with the same priority should function as a loadbalancing ... > This is high end, should keep transit latencies down to 14 to 20 seconds per email. <FE> 3GHZ Dual core, mirroring, put /var/spool on separate spindles, redundant power supplies, MX weight 10 Pretend it's a normal postfix server, depending on distro, 2/4GB ram, (remember, its running your only copy of mysql, and will have your quarantined files via NFS or SQL) Keep an updated copy of your userlist on <FE> to block dictionary attacks. Use tarpit :-) Maybe use postfix mime-header rules to block certain attachments MS should never have allowed in email. (.bat, cmd, scr, pif). I would do a very heavy reliance on postfix to block as much as you can. <SA1 and SA2> 3GHZ dual core, I don't know if I would go for mirror and redundant ps, since you have two of them. Maybe 2/4GB reach. <Mail server> Don't know, what do you have now? What is latencies? The above should reduce the load by 90%. _______________________________________________ AMaViS-user mailing list AMaViS-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/amavis-user AMaViS-FAQ:http://www.amavis.org/amavis-faq.php3 AMaViS-HowTos:http://www.amavis.org/howto/
