a small gesture to play nice with the rest of the world. Why rely

Not a direct answer but the domain in question has an Email verification
API. They are definitely probing for valid users.
I wonder if there's ever a valid use case for this. However, if you wanted
to allow you would just enable the VERIFY feature.

I removed a bunch, but might have missed some. That "command_directory"

One other thing while I wait...
Once I'm done researching (in a week or two), I'd like someone to provide a

I am doing a deep dive on mail hosting and this includes Postfix. I have
