Two option files can be used for both the delivery status and message disposition notification. These are intended to make internationalization of generated notices more flexible. They are as follows:
IMTA_LANG:return_option.dat (DSN)IMTA_LANG:disposition_option.dat (MDN) |
The options available for these files are described in Table 10–10.
Table 10–10 Delivery Status and Message Disposition Notification Options
Option |
Description |
---|---|
DAY (DSN) |
The text to insert for a %U or %u substitution when RETURN_UNITS=0 (the default) is set. Note that no distinction is made between %U and %u (unlike the default case where English “Day” or “day”, respectively, would be substituted). |
Override for the “Diagnostic code:“ text used in the construction of the per-recipient section of the first part of a DSN. This field should be specified in the same charset that’s used for the first part of the DSN. |
|
HOUR (DSN) |
The text to insert for a %U or %u substitution when RETURN_UNITS=1 is set. Note that no distinction is made between %U and %u (unlike the default case where English “Hour” or “hour”, respectively, would be substituted). |
n.n.n (DSN) |
When constructing the per-recipient part of a DSN a check will be made to see if there’s an option whose name matches the numeric per-recipient status. If there is the corresponding text will be inserted into the DSN. Additionally, if the REASON option specified above produces a zero length result the REASON field will not be inserted. |
Override for the “Original address:” text used in the construction of the per-recipient section of the first part of a DSN. This field should be specified in the same charset that’s used for the first part of the DSN. |
|
REASON (DSN) |
Override for the “Reason:” text used in the construction of the per-recipient section of the first part of a DSN. This field should be specified in the same charset that’s used for the first part of the DSN. |
Override for the “Recipient address:” text used in the construction of the per-recipient section of the first part of a DSN. This field should be specified in the same charset that’s used for the first part of the DSN. |
|
Override personal name field to be used in conjunction with the From: field. This field should be RFC 2047 encoded. The value set by the RETURN_PERSONAL MTA option is used if this option is not specified. |
|
SUBJECT (DSN and MDN) |
Override Subject: field. This value will only be used if the notification didn’t provide a subject field of its own. This field should be RFC 2047 encoded. An appropriate subject will be constructed if this option isn’t used and the notification didn’t provide one. |
Charset text for the first part and subject of the MDN should be converted to. The default is not to perform any conversion. |
