Hello in there, >on http://www.ipswitch.com/products/IMail_Server/sysreq.html IPswitch says: This goes back to, oh, 1997 when PII was top of the line AND AND AND there was no IMAP and no webmail in Imail. There was only highly efficient pop (basically empty/tiny mailboxes) and smtp, for which the numbers of the table are probably quite right. >............... > >We have about 1500 Users on a Dual Pentium 100, 128 MB RAM. >It works hardly, but it's not nice at all. because you run webmail and/or imap, both of which are big processes to execute on the server, both of which encourage the users to leave their mail on the server, meaning reading the .mbx files to find the headers is a heavy disk i/o task. imap and webmail are your worst enemies. Asymmetric multi-processing, aka IMGate, is your first step to scaling imap/webmail. Moving webmail to an external box(es) is also good, but HKSI has spoiled/nailed, in the nicest possible way :)), everybody NOT to displace webmail off the mailbox server. The mail server system design to support large imap/webmail populations is critical.
