Hi Everyone,
I'm running a Postfix+Dovecot+SpamAssassin box in a DMZ. Everything is honkey dorey. Lately I've been thinking about moving Dovecot (for IMAP) into the internal network - I'd rather not store my mail on the CentOS 4 host in the DMZ.
Why?
Not having done this before, I'm not quite sure what options I have. Also, I don't know if this is a good idea at all. So:
- Should I just leave mail storage on the same box in the DMZ?
Tell us why you want to move first.
- If the answer to 1 is no, what's the best way to get mail from the
SMTP server in the DMZ to an IMAP server in the internal network? Here's what I've briefly considered:
DMZ Postfix+SpamAssassin -> Internal Postfix+Dovecot DMZ Postfix+SpamAssassin -> Internal Fetchmail+Dovecot
Forget this. Answer the question first and then you can come to this after you also consider your hardware.
- Any tutorials for this out there, or even articles, etc., discussing
using Postfix as a gateway? So far, I haven't found any that I've liked.

It is a little bit involved. But first answer the question of why you want to move before we explore this.
