You can see from it that exim's host opens a TCP connection to the

I can't imagine how to produce such
behaviour with socket API.
Neither do I. Moreover, the problem began after upgrading the OS from
FreeBSD 11 to 12.2-RELEASE-p1, and exim to exim-4.94_4. Maybe the OS is
to blame.
Can you manage to get a syscall trace of exim's actions, isolating those
for that specific socket?
