Hi Eriks,

Obviously, something did change or you would not be having a
problem. :) The harder part is to discover what changed and how
it is affecting your system. Those odd mailq entries if they
are being fed to RT could bump the load on your system. Do
you have any kind of filtering pre-RT to prevent bogus mail
from hitting the RT server?

Regards,
Ken
