Cyrus, yes via lmtp. I have only tested it so far with 6 deliveries, and
it has all done in less than 1 second. I suspect that a delay may be cyrus/sasl
talking to M$ Active Directory (which is on another machine of course).

I do NOT know if there will be a problem, the largest 'common' delivery
that I expect is about 200, it prob doesn't matter if the 'all' (of several
thousand) takes some time.

I will post results here (along with hardware description) when I know them.
