I'm looking for feedback on experiences of implementing an enterprise mailHI Chris,
server with IMAP and webmail, preferably groupware, on our Dual Xeon Fedora
server. We currently have sendmail, uw-imap, squirrelmail, in standard
Redhat configuration, and we are having huge load problems as the present
setup is not capable of supporting the needs of our users. Large mail
folders bring the server to it's knees. We only have 25 users but they
travel and use the mail system as a filing system, routinely saving 10MB
emails and never cleaning up old mail.
We're currently using postfix + cyrus-imap + squirrelmail. We have about the same number of users many of whom travel on a regular basis. Many of our users keep large quantities of mail on the mail server (several hundred MBs is fairly common for a user). Our setup also does spam checking/blocking, defanging (removing potential executables) and virus checking. We are also using a Dual Xeon system, but ours doesn't even seem to be breaking a sweat. We've found the combination of postfix and cyrus-imap to provide very good performance..

We also need more groupware type features such as file sharing, messaging
and calendaring. I am looking at Binari, Groupwise, Surgemail, and
opengroupware which would involve more work to implement for me.
If you have spent time researching mail and groupware I would love some feedback to save me time and help me find a suitable application.
