Paul,
Yep. That's what I mean. I'm still learning the language and the tools.
All this to avoid being greylisted when I send mail to domains that check
for authentication.

Where does this go? I'm not forwarding mail through another mail server so
the port should be 25 ... I think. I believe that I need to also set a TXT
record on my DNS server for SPF and, perhaps, one for DMARC. Much to learn
and looking for resources.

I don't know what postfix is using here. I have the router set to forward
incoming mail through port 25; outgoing mail uses teh same port. I've not
explicitly set SSL or TSL for alpine/postfix.

I've installed opendkim but have not yet started it.
