Only reply emails are rejected in this manner. New mail to the same
recipients works fine. I can't seem to figure out why replies are being
rejected. Any info you all could provide regarding the resolution of
this issie would be greatly appreciated.

The message should contain a web address for you to check to see if you have
a problem on your end or if it is your ISP. Normally, it is because your
ISP or IP is on an RBL.

Make sure you're authenticating to your outgoing server.
