The big news for some of us is that Exim has been dropped from ports. Here is a good article about transitioning from Exim to OpenSMTPD:

I tried using OpenSMTPD a long time ago, shortly after it came out, but things were not stable enough. I guess it is time to give it another go...

OpenSMTPD was substantially rewritten in 6.4 (2018). It is the best SMTP server for the majority of use cases. Unfortunately, the portable version has been weakly supported, so it's usually only OpenBSD users than learn how great it is.

I'm happy with it. Been running OpenSMTPd for many years at this point, on both OpenBSD and Linux, and I have no complaints.

I've also started using OpenSMTPD on linux machines when I need a simple MTA (which is to say, in almost all cases).

I really like OpenSMTPD; no nonsense and configuration feels rather modern compared to the legacy stuff that's out there.

Surprised exim was dropped from ports. It is not like it was ever in base. I guess the maintainer did not want to anymore.

We don't have to guess. There are several mailing list discussions:
