Understood.  However, most everyone here in my office (a mortgage
company of
about 25 people) can barely even spell the word computer much less
use one
effectively.  And, aside from that, I am running these tests from my
windows
client, so I can verify that it is configured correctly for the
purpose of
running these tests.  Although I wish it were as simple as someone
using a
different SMTP server....it would make my life easier :P

Have you physically used this offending persons work PC during off
hours
and investigated just how they have their outlook explorer
configured???
