I would do some tests on basic mail... Telent to the box on port 25
and see how long it is before you get the greeting. Do the smae on the
box to an outside machine. Both should be *very* fast. If they are
not, look into reverse resolution of the ip address of the mailman

qrunner can only deliver mail as fast as the mta, so look there also.
