Specifies the source of queued message information for subsequent directory commands.
Available only in interactive mode.
view -database | -directory_tree
By default, queued message listings are generated by scanning the imta/queue/ directory tree. This corresponds to the -directory_tree option. You can, alternatively, generate the listings from the MTA queue cache database by issuing the -database option.
Settings made with the view sub-command remain the default until either another view command is issued or the utility exits. The default may be overridden with the -database or -directory_tree options of the directory command.
Note that the directory tree is always used when listing held message files.
