Too many professional bulk mailers on all those lists. I for one don't like the documentation runaround. There's a lot of stuff that's getting more complicated than it needs to be. I need SPF+DKIM+DMARC for basic spam control.

I have a setup like that myself. Nothing to do with Dovecot. It's entirely up to postfix which mailbox to deliver incoming messages to, and the user's client to address outgoing mail with a proper ID.

The performance of flat files really bogs down my system and causes me to lose mails if too many arrive or if the file grows too large.

Without a doubt there are many useful tricks and tutorials out there. I have found several very helpful.

Maybe a future programming project idea: I want a system that will store all mail messages and user account info in, say, a postgresql transactional database, a little more manageable and reliable than ad hoc databasing with those flat files all over the place cluttering up the system.
