I double-checked that I did not have a typo there. In any case I would expect
to see the "too many messages" lines cropping up frequently if I had it set to
one. I have another question about smtp_accept_max_per_connection but I'll put
it in another message.

I do not have the same build of Outlook available on a convenient PC and it is
difficult to get users to set these sorts of things up to test. I was hoping
someone might have encountered the situation before and worked out what was
happening.
