(OK, I messed up with my subscription to the list and ended up looking
like a fool. I used to read the list through a mail to news gateway, but
found it best to get it into my mailbox.)

I didn't really expect anything else. However I would really avoid ending
up telling my client that they need a cluster of mailserver if there is
plenty of experince saying that is should be running nicely on a medium
sized server.

I consider this higly usable information.

Of course I and the other people working here have to think and do our own
evalution, but systems having much more than 50.000 user is rather rare, at
least here in Norway. Collecting some information about what others are
running appears to me as a good idea :-)

Of course, but I still found you information highly usable.
