I hate people that "me too", but me too :) We've got a dual 1.4 GHz box with
4GB or ram that runs consistantly under 2 or 3 load average. But sometimes
when the volme of incoming mail greatly increases, the single Mailscanner
process has a hard time keeping up. I know there are locking issues, but
we would be happy to help work through these and to beta test code. Thanks.<br>
