Performance question...

This rings a bell.

His test system is a Pentium 200 with less than 10 users and just auto generated
test messages.  The mail boxes were growing to least with the
Courier setup.

Any other info would be great and thanks for the note.

BTW the eventual production system is a dual Xeon 3.0GHz with 4GB ram and 15K
drives for about 5000 users.
