DEQUEUE ACCESS mapping table

New in 8.0.2.3 is the  mapping table, which is consulted at the beginning of message dequeue processing.

The default probe for the  mapping is of the form: channel&#x7c;filename&#x7c;queue-time&#x7c;envelope-from&#x7c;auth-parameter&#x7c;auth-sender&#x7c;priority&#x7c;domain where   is the channel from which the message is being dequeued,   is the full  file name of the message,   is the  approximate time in seconds that the message has been in the queue (or    if that value cannot be determined),    is the envelope From address for  this message,    is the unencoded  value of any MAIL FROM AUTH= parameter associated with the message,    is the mail address associated with any authentication identity used to  submit the message,   is the MT-priority value for the message, and    is the DNS name of the server to which the  message is to be sent. Note that the  MTA option, if set, will cause any vertical bar characters that would have been in the   ,  ,  , or   fields to be replaced by the specified character.

As of MS 8.0.2.3, the $R input flag will be set if the message is being accessed in read-only mode by a utility such as imsimta qm.

If bit 11, value 4096, of the  MTA option is set the probe changes to include the conversion tag for the message: channel&#x7c;filename&#x7c;queue-time&#x7c;envelope-from&#x7c;auth-parameter&#x7c;auth-sender&#x7c;priority&#x7c;conversiontag&#x7c;domain New in MS 8.0.2.3, if bit 1, value 2, of the  MTA option is set the probe changes to include the count of previous retries for the message: channel&#x7c;filename&#x7c;retry-count&#x7c;queue-time&#x7c;envelope-from&#x7c;auth-parameter&#x7c;auth-sender&#x7c;&#x7c;prioritydomain If $N is set by the mapping the current dequeue action is aborted without incrementing the retry count. If $S is also set a new backoff time in seconds, expressed as an integer, is read from the mapping result string.
