HOWEVER, the same section states:
"Whenever an SMTP transaction is used to send a DSN, the MAIL FROM command
MUST use a NULL return address, i.e., "MAIL FROM:<>"."
A proper intepretation of that statement requires its full context. The intent
is to prevent message looping. As such the CRI or other systems SHOULD ensure
that specfied addresses do not violate that tenet.
The envelope sender address of the DSN SHOULD be chosen to ensure
that no delivery status reports will be issued in response to the DSN
itself, and MUST be chosen so that DSNs will not generate mail loops.
Whenever an SMTP transaction is used to send a DSN, the MAIL FROM
command MUST use a NULL return address, i.e., "MAIL FROM:<>".
That means that C/R systems such as yours MUST support the empty return
path (<>).
No it does not, IMO, given the full context of the requirement.
