MH-C-REPORT
MH-T-MTS-IDENTIFIER
Is the MTS identifier of the message or probe. This attribute is the same as the like-
named attribute of the message or probe.
MH-T-ORIGINAL-EITS
Provides the EITs of the MH-T-CONTENT attribute that were present when the 
message was submitted. This attribute is present only if the message content was 
converted or, in the case of a probe, would have been converted for one or more of the 
recipients to which the report applies.
MH-T-PER-RECIPIENT-REPORTS
Are delivered per-recipient reports, one for each recipient to which the report applies.
MH-T-REPORT-ADDITIONAL-INFO
Is binary data that follows the BER, except the minimum value length is 2 octets. You 
can specify a zero-length octet string as hexadecimal ‘04 00’. This attribute is present by 
bilateral agreement between the MD that originates the report and the MD serving the 
originator. The agreement includes specification of the data type of the attribute value.
MH-T-REPORT-DESTINATION
Is the O/R name of the report’s immediate destination. The MTA that originates the 
report initializes this attribute either to the last O/R name in the MH-T-EXPANSION-
HISTORY attribute, if it is present in the message (or probe), or to the O/R name of the 
originator of the message or probe.
MH-T-REPORT-EXTERNAL-TRCE-INFO
Documents how the report was processed by each MD that transferred it. The entries 
appear in chronological order; the first entry is from the MD that originated the report. 
An MD may add one or several trace entries, as follows:
•
If the report 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 report 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 report to one 
or several MDs.
You can use this attribute to detect loops.
MH-T-REPORT-INTERNAL-TRCE-INFO
Documents how the report 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. The entries appear in 
chronological order.
