Postfix
Contents
Purpose
General Postfix notes collected while building a self hosted mail solution.
Infrastructure Overview
I am forced to use Comcast cable at home, obviously no one in their right mind would allow email sent from this network. I settled on placing the sending MTA relay in the could, while using the same relay in conjunction with an MTA at home for receiving emails. The MDA will be on on prem as well running only IMAPS and a web client that is TBD.
Basic Postfix Receive Emails for Domain
For receiving emails for a domain and delivering them locally.
MTA Relay
Running Rocky Linux on Digital Ocean.
Virtual Domains
[1]This prevents delivering to local system accounts, which will be important as I will want to manage the accounts independently of the mail servers themselves.
Adding users
Maildir
[3][4]This will be helpful for structuring emails without additional infrastructure.
