Queue cache mode MTA option

File format MTA options:  (integer)
RESTRICTED: The value 2 (the default) must be used for the Messaging Server MTA.

The  MTA option tells the MTA the type of cache of message queue files to use. In particular, a value of 2, the default, means that the Job Controller  is maintaining (in-memory) queue cache information. This option must not be set to any other value.
