Subject: Little problem


Hi all
I have a problem and I hope that you can give me some directions to try.

This is the problem

Exchange 5.5 SP4 and a Redhat 7.2 box running the intranet and send
mail. The intranet computer contains a mailing list program that picks
names from a membership database and sends mail to those addresses
designated. Up until 2 weeks ago it was all working fine but this is
what is happening.
The system has started generating error messages.   

Nothing has been changed on the exchange system.   I have checked the
DNS
and all normal mail goes through the exchange with no problems.   The
relaying in the exchange is also set up for relaying from the IP address
(Internal).   I have even added a host file with the internal ip address
and
name of the send mail box.

I have turned on maximum logging to find out what is going on and have
the following logged errors

Bounced message

 The following recipient(s) could not be reached:
