Aha, right. You're running on too old a kernel, and I can use that
result (from the setsockopt) in children of the daemon to condition
use of sendto() (TFO active connections) for auxilary connections
(such as to rspamd). I should probably override transport configuration
of hosts_try_fastopen too.

Presumably you'd not set hosts_try_fastopen; the default in 4.88
is empty.
