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><BR>David Lee wrote:<BR>
