If you're looking for a package, you might want to try zimbra. It's awesome with both a OpenSource and supported version. I've worked with several and find it to be one of the best.

I am currently using Sun's JES suite for ldap/email/calendar. Every other box I manage is Red Hat, and I am interested in what other's are using for this. Cost is the biggest issue, but we do need some level of support. We use ldap for many other internal application authentication and authorization. We are migrating towards Kerberos for authentication and still wanting to use ldap for authorization, but JES mail/calendar doesn't support Kerberos. So a solution that does would be nice. Currently all is run on a single T2000, which handles the load easily, but I would like to move towards a separate box for each service and be able to scale it easily for performance and redundancy. TLS/SSL is a must for not just authentication but all internal email traffic. I realize kerberos will handle this for us if we can get email to it. I use a separate box at our gateway for spam/virus filtering.
