FWIW, I submitted a PR to update the MacPorts' version of OpenSMTPD to 7.3.0p0 here:

https://github.com/macports/macports-ports/pull/19180

It appears to have passed the CI/build bot checks OK at least!

I don't have commit access within MacPorts, so it will be up to someone else to merge it. Hopefully the maintainer will take a look at it too (though since I opened that Trac issue 8 days ago for RC2 to facilitate testing I have observed no comment).

I did test building it with both MacPorts' libressl-devel (which is at 3.8.0) and openssl3 (which is at 3.1.1 currently) and it seems as if that was OK, so hopefully my modification to use MacPorts' dylib (which allows for different TLS libraries) was sufficient.

Alas, I am still not presently in a situation to be able to actually test any MXes; so the best I can offer from my present vantage is build testing, not functionality testing.

C'est la vie!
