Jorge, Thanks for the reply.
However, I am pretty certain this is not a relay issue.
We are not configured to relay.
Along withthat, we have been running error free until
this happened.
After a reboot things started clearing out and mail is
flowing fine.
This to me signifies an SMTP issue, not a relaying issue
and though things are working right now, I would like to
know why this happened so I can prevent it from happening
again.
