My company is looking for an email solution to replace our 3rd pary mail system (currently runs on Windows). I was thinking about putting in a Xserve running mail services, but I don't know much about it. My requirements are: 1. Support for up to 200 POP3 OR IMAP accounts 2. Ability to foward mail (message goes to recipient and then is forwarded to a different account on a different server). 3. Support for MS Outlook Optional things that might be nice 1. Ability to query or connect to a LDAP server. We run AD right now. Has anyone implemented something like this? Would it work for me?
