Well the answer is I don't know....
However an interesting point is that all the hints files will be
updated, meaning that when the queue runner hits the first
message/address routed for mx1.example.com it will then normally pick up
the other messages with addresses waiting on mx1.example.com and push
them down the same SMTP connection.
How this interacts with the max_parallel settings, and TLS/SSL is an
interesting set of questions which early in the morning after a very
late night I am not equipped to deal with :-/ [Switching off all
outgoing TLS/SSL support on a mailing list machine may well be a good
plan, although I *like* the idea of making things more difficult to look
