MH-C-MESSAGE
MH-T-EXPANSION-PROHIBITED
Indicates whether the originator instructs the MTS to issue a non-delivery report rather
than expand a distribution list in the case that a recipient’s O/R name denotes a
distribution list rather than a user.
MH-T-EXTENSIONS
Are requests for extended processing as part of the object’s submission, transfer, or
delivery.
MH-T-EXPANSION-HISTORY
Is a record of each attempt to add recipients to the distribution list of the message. The
expansion records appear in chronological order.
MH-T-EXTERNAL-TRACE-INFO
Documents how the message was processed by each MD that transferred it. The entries
appear in chronological order; the first entry is from the MD that originated the message.
A single MD can make one or more trace entries.
An MD may add one or several trace entries, as follows:
•
If the communication is transferred to the MD of first choice, the transferring MD
adds a trace entry with an MH-T-ACTION attribute value of MH-AC-RELAYED.
•
If the communication is transferred to an MD that is not the first choice, the
transferring MD adds one or more trace entries with an MH-T-ACTION attribute
value of MH-AC-REROUTED. These entries indicate attempts to transfer the
communication to one or several MDs.
You can use this attribute to detect loops.
MH-T-INTERNAL-TRACE-INFO
Documents how the message was processed by each MTA that transferred it. However, a
service can limit the scope of this attribute to the local MD, except that the scope of each
entry documenting expansion or redirection is global.
An MTA may add one or several trace entries, as follows:
•
If the communication is transferred to the MTA of first choice, the transferring MTA
adds a trace entry with an MH-T-ACTION attribute value of MH-AC-RELAYED.
•
If the communication is transferred to an MTA that is not the first choice, the
transferring MTA adds one or more trace entries with an MH-T-ACTION attribute
value of MH-AC-REROUTED. These entries indicate attempts to transfer the
communication to one or several MTAs.
•
If the communication is redirected to an alternate recipient, the transferring MTA
adds a trace entry with an MH-T-ACTION attribute value of
MH-AC-REDIRECTED.
This attribute can be used for detecting loops.
