Message Backups and Spam Checks

[Steve Evans]

I had a lot of problems with backed up mail today.  CPU usage was low,
and there was plenty of free memory.  When I changed MailScanner.conf to
Spam Checks = no it quickly processed all the queued mail.  So I assume
that one of the net checks (RBL, Razor, or DCC) was causing problems.
My question is how can I tell when one of the net checks is causing
problems and how can I tell which one?
