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.
If you are on it, check if firewalld got installed and is running. It
has it's own firewall and some VERY illlogical settings. a "iptables -L"
won't help you with that.
