+
+    RMAILBX         A <domain-name> which specifies a mailbox which is
+                    responsible for the mailing list or mailbox.  If this
+                    domain name names the root, the owner of the MINFO RR is
+                    responsible for itself.  Note that many existing mailing
+                    lists use a mailbox X-request for the RMAILBX field of
+                    mailing list X, e.g., Msgroup-request for Msgroup.  This
+                    field provides a more general mechanism.
+
+    EMAILBX         A <domain-name> which specifies a mailbox which is to
+                    receive error messages related to the mailing list or
+                    mailbox specified by the owner of the MINFO RR (similar
+                    to the ERRORS-TO: field which has been proposed).  If
+                    this domain name names the root, errors should be
+                    returned to the sender of the message.
+
+    MINFO records cause no additional section processing.  Although these
+    records can be associated with a simple mailbox, they are usually used
+    with a mailing list.
