--- Comment #8 from Jeremy Harris <jgh146exb@???> ---
It would be, yes. I don't see the log; did you actually attach it to the bug?
However, this issue may be already partly fixed: that flag-setting is moved to
early
on in main() in current HEAD, so the unsetting done in daemon_go() will not be
overridden.

We're still left with the case of a command-line sourced message being sent
over
SMTP/TCP. TFO will be attempted and with your (odd?) case of an exim built for
a modern Linux being run on an old kernel, will fail. It should be spooled,
and
the daemon would be avoiding TFO so it's only a delay - but the fix is simple
so
we may as well bulletproof where we can.
