I have 10+ years of NT networking (even some Unix back in '92) - I have 5 clients that I'm sub-hosting via a large player and now I'm looking to do it myself. I already support the clients from a networking perspective. I have a Linux box built with RedHat 9 and apache loaded (not 100% configured yet). I've read about virtual domains and think I can get that going, but my question is how I would handle the mail in a virtual hosting environment. All my clients have their own 602Software e-mail servers that SMTP via the current webhost. How would I duplicate that setup inhouse so I don't have to make tons of changes on the client end?
