I'm looking for feedback on experiences of implementing an enterprise mail 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 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. Chris Mason -- No virus found in this outgoing message.
