RE: [Exim] Mail Delivery Failure...

My apologies everyone, I figured out the problem. I had an e-mail account
configured to send through a previously canceled netzero account, so it was
qmail at smtp.netzero.net. I didn't figure it out until I googled the error
message and it brought up qmail multiple times.
