I have approx 500 users. Of which probably only about 300 will be connected at peak times, but they will be consantly connected in the "check for new mail every 5 minutes" sense. Overall the system will deliver about 25 - 40,000 messages a day. There will be a seperate SMTP server delivering to this via LMTP, and a seperate webmail server connecting in through IMAP. Quota's will be set around 250MB and the use of sieve filters will be enabled. All with authenticate against our LDAP server (its not purchased yet, but it'll be novell edirectory).
My major question is what kind of hardware will cyrus require to handle that level of load? Currently we were planning on buying a dual 3.0GHz Xeon system with 2GB of ram running RHEL 3.0. For storage it'll connect via HBA to our EMC CX500 storage array. Will that do it? Does anyone have anything similar setup?
One other question, is it possible to have the one IMAP server listen for both encrypted and unencrypted connections? We'll then use firewall policies to make sure anything from outside the lan is SSL'd.
