So replace it with Postfix? I've been using it (on Debian Linux) for decades
without any problems. AFAIK, it doesn't do anything pathological like that.
It just reads its config and starts waiting for email.

If properly configed, shouldn't things come up in order, with their
dependencies already running? Or is specifying boot order not possible on FBSD?

I can certainly understand the possible need for SSH, just for incase, but
I'd think things could be set to do stuff in the proper order. Except for
cyclic dependencies, of course -- a significant bug for the maintainers.

Yes; that's done with rcorder(8). The startup order isn't completely
defined, just the dependencies that require being started before (or,
occasionally, after) some other service.

The discussion here is whether the "proper order" should be changed
from
the current default. As for cycles in the graph, rcorder already detects
that.
