subject: SMTP non-delivery report
I have a CLP which does a SNDDST (then hands to Exchange Server) -
occasionally send a fixed message to about 400 Suppliers.
I have run this many times in the past, but now it only seems to be
working if I use an Email address of one of our internal Users.
If I now use an external email address, the exchange server message
tracking log reports: SMTP: 'Non-Delivered Report (NDR) generated',
and no email goes to the external address.
However, email mail routing exclusively thru exchange IS working both
- inbound and outbound.
