Thanks for the tests and patch. If buffered I/O doesn't work properly,
then I would plump for changing to unbuffered I/O regardless. I don't
think we need to mess with the complication of having an option. I agree
about unbuffered I/O and sockets (I didn't write the Dovecot code).
It might be best to change to using send() and recv(). (Or ip_recv(), an
Exim function that calls recv() under a timeout.) I'll take a look at
this sometime soon.
