The return address used by Messaging Gateway (SMG) for non-delivery report (NDR) emails and delivery status notifications (DSN) needs to be changed from the default value of "postmaster".
Messaging Gateway provides a means to update the postmaster email address included in the body of NDR and DSN messages generated by Messaging Gateway via the Control Center's Protocols > Settings page. The default value of "postmaster" results in the following format for NDRs.
Note: this configuration option does not change the email return address for NDRs and DSNs which is hardcoded to "Mailer-Daemon@smghostname".
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to <postmaster>
If you do so, please include this problem report. You can
delete your own text from the attached returned message.
<firstname.lastname@example.org>: 550 5.1.1 <email@example.com>: Recipient address rejected: User unknown in local recipient table
-------- End of the Message --------
The <postmaster> entry in message body is the field modifiable by Bounce Customization.
