--- Comment #4 from Jeremy Harris <jgh146exb@???> ---
The apparently working FreeBSD animal is 11.0 but, hmm, is not claiming to
support TFO in Exim despite having TCP_FASTOPEN in /usr/include/netinet/tcp.h
So that explains it not falling in a heap; I assume the runtime test (exim
does a setsockopt(.., TCPFASTOPEN...) to check on the feature) is resulting
in that codepath being avoided. You're right that MSG_FASTOPEN doesn't
seem to be defined. Perhaps just complexifying the #ifdef TCP_FASTOPEN would
be simplest.

Any info you can find on how TFO is supposed to be coded for in FreeBSD would
be useful.
