I suggest moving this to mailop, where it arguably belongs. But I'm
going to follow up on a few points, anyway.
First, I forgot to mention two other highly effective mail system
defense methods: geoblocking and passive OS fingerprinting.
Geoblocking: A mail server for a local construction
Thanks to everyone for all the tips and info. I think I have compiled
plenty of info to get this done. I will probably start with some of
the basics and see how things go. THen as needed start putting in some
additional features as I see how things progress.

Using DKIM is a good idea. Do *not* use ADSP. It is a failed
experiment which will provide no benefit and considerable pain.

Don't do DMARC if you expect to have end-users forward emails, or
subscribe to mailinglists. Despite the removal from the current DMARC
spec, the
MX, PTR, and SPF are really all you need.
So far so good, noting that a host name that doesn't look generic is
better than one that does.
