Hello,
I currently have a mail server with Postfix and Dovecot installed in the same jail. I was considering breaking the jail down to a dedicated mail server (jail) with the other jail the running Postfix.
I know that on the same server or jail the configuration is fairly easy, but I haven't been able to find much documentation on breaking them out. Is it simply setting up the Postfix jail as a relay which requires authentication? If so, is it simple to allow for the authentication to use the same account credentials used in Dovecot?
If someone has a simple example or manual reference that they could forward me to, please let me know. Also, I'd like an opinion on if this makes sense from a security standpoint or if I'm just wasting my time on a project like this. I believe the isolated Postfix jail makes sense as I would assume that would likely be the preferred attack vector for sending spam or malware if compromised.
