MH-C-MTS-IDENTIFIER
MTS indicates delivery through the message transfer system. The other names indicate 
types of terminals.
MH-T-RECIPIENT-NAME
Is the recipient’s O/R name.
MH-T-RECIPIENT-NUMBER
Is the ordinal position of the recipient in the list of recipients originally specified by the 
originator of the message. For the first recipient, the value is 1. The minimum value is 
ZGPI-MIN-RECIPIENTS, and the maximum value is ZGPI-MAX-RECIPIENTS.
Implementation and Usage Notes
•
The MH-T-PREFERRED-DELIVERY-MODES attribute is a 1988 extension 
attribute. It is named RequestedDeliveryMethod in Recommendation X.411. All 
other extension attributes in the MH-C-MESSAGE-RD class are mapped to values 
of the MH-T-EXTENSIONS attribute. 
•
Recommendation X.411 recommends that the criticality setting of the 
MH-T-PREFERRED-DELIVERY-MODES attribute be critical-for-delivery. 
MH-C-MTS-IDENTIFIER
This class defines an MTS identifier that distinguishes a message, probe, report, or 
P1-encoded object (root object) from all other root objects, regardless of their class, 
ever conveyed by the MTS. The MTS identifier is assigned by the originating domain, 
the MD at which the message or report originated. For example, when you transfer a 
root object out to the GPI service, the GPI inserts an MTS identifier in the object (unless 
one is already inserted).
Table 3-29
