No need to hammer the man.

For this application of a million mails in, say, an hour, it would
make sense to have multi-message queue files. If Postfix could
handle multi-message files, then it could speed up very much because
most of the time now is spent in create/rename/remove overhead.

Direct queue injection would also help to keep the amount of
necessary hardware under control.

Not that I will be able to afford one, but what's the ballpark
price for such things nowadays?
