 RFC 3464             Delivery Status Notifications          January 2003
 2.2.2 The Reporting-MTA DSN field
 
          reporting-mta-field =
                "Reporting-MTA" ":" mta-name-type ";" mta-name
 
           mta-name = *text
 
    The Reporting-MTA field is defined as follows:
 
    A DSN describes the results of attempts to deliver, relay, or gateway
    a message to one or more recipients.  In all cases, the Reporting-MTA
    is the MTA that attempted to perform the delivery, relay, or gateway
    operation described in the DSN.  This field is required.
 
    Note that if an SMTP client attempts to relay a message to an SMTP
    server and receives an error reply to a RCPT command, the client is
    responsible for generating the DSN, and the client's domain name will
    appear in the Reporting-MTA field.  (The server's domain name will
    appear in the Remote-MTA field.)
 
    Note that the Reporting-MTA is not necessarily the MTA which actually
    issued the DSN.  For example, if an attempt to deliver a message
    outside of the Internet resulted in a non-delivery notification which
    was gatewayed back into Internet mail, the Reporting-MTA field of the
    resulting DSN would be that of the MTA that originally reported the
    delivery failure, not that of the gateway which converted the foreign
    notification into a DSN.  See Figure 2.
