Mail queue files
Each message in the queue has a number of files associated with it.
The files are named according to the following conventions:
TypefID
where ID is a unique message queue ID, and Type is one of the following letters indicating the type of file:
Item | Description |
---|---|
d | The data file containing the message body without the heading information. |
q | The queue-control file. This file contains the information necessary to process the job. |
t | A temporary file. This file is an image of the q file when it is being rebuilt. It is quickly renamed to the q file. |
x | A transcript file that exists during the life of a session and shows everything that happens during that session. |
For example, if a message has a queue ID of AA00269
