Upgraded from 4.38 to 4.50 and WOW

[Greg Deputy]

I upgraded my MailScanner installation last night from 4.38 to 4.50.
It's a fedora box running postfix, and a smaller machine (p3 with 512M
ram) that has been pretty much at capacity.  Before the upgrade, the CPU
utilization averaged 75%.  After upgrading, the CPU utilization has
dropped to 25%!  The only thing that has changed is the MailScanner
version.  Looks like the recent changes have REALLY made a difference!

MailScanner rocks.  Thanks Julian!
