Yeah, I noticed that. Locally I didn't encounter any issues, but I am using LibreSSL.

It seems plausible that perhaps OpenSSL testing is considered a second class citizen TLS library given the notes (from CHANGES.md):

`Dependencies note:

It's preferable to depend on LibreSSL as OpenSMTPD is written and tested
with that dependency. OpenSSL library is considered as a best effort
target TLS library and provided as a commodity, LibreSSL has become our
target TLS library.`

Perhaps OpenSSL and LibreSSL have skewed too much in the past decade and change? It wouldn't be the first time such issues have cropped up. Perhaps moving away from the dylib approach is one potential fix, explicitly declaring a LibreSSL dependency instead?
