All,

First off I love what the developers are doing with dbmail. An awesome
idea that addresses several issues I have been having with retention and
centralized storage with almost infinite scalability.

My only issue was performance coming from using a courier-imap with
postfix. 

Now, with these index additions of Paul's has improved my performance to
almost the same as courier-imap. Has anyone had any issues with these
modifications? Are there any draw backs the the indexes?

I plan on making dbmail the center piece of a scalable mail hub that
will include other feature and am wondering what kind of large scale,
both number of users and message throughput per day, people have set up
and in production.

Thanks for all the great information on this list and the the dbmail
developers, keep up the excellent work.

Thanks again,

Rich
