We have the need to deploy a linux-based email server (SMTP, POP, IMAP, Web interface) for linux. We've been trying to cobble together stuff from the free-ware inventories, but we might be better off with something commercial. Any suggestions on a commercial program or two that can handle maybe 100,000+ users in many multiple virtual domains and function within a cluster? Price isn't the object, functionality is. =-=-=-=-=-= Robert Hayden [EMAIL PROTECTED] UIN: 16570192 -- To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject.
