At a previous employer, they had a pair of NetApp F840's with hundreds of thousands of mailboxes, mostly accessed via POP3. There were 2 Exim MX receivers (now upgraded to four), 3 POP3/IMAP servers, 2 sqwebmail servers, plus other boxes not related to mail (e.g. homepages, radius, signup) Those were low spec boxes by today's standards - P3 733MHz IIRC. They were running FreeBSD 4.x. You need at least two of everything, of course, for resilience. Keeping MX, POP3/IMAP and webmail separate makes it much easier to monitor and scale, and for overloads in one part of the service not to affect other parts of the service. In front of these boxes were Foundry Serverirons for load balancing (except for MX, which doesn't need a load balancer - just list multiple MX equal-priority MX records) HTH, Brian. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
