Bad settings.

Having REFUSE_LA higher than QUEUE_LA is a surefire way to kill your server.
Most busy SMTP servers are I/O bound, and running in queue-only mode does
nothing to reduce your I/O load.  In fact, it *increases* it because the
messages will need to be pulled from the queue at some point in the future.
See "Sendmail Performance Tuning" by Nick Christenson.

If you're running Linux, and those settings work well from you, your
mail server is *not* busy! :-)

Regards,

David.
