To disable a handler, run the following command:

# ./mail_handlers_control --disable
    --name=<handler name>
    --type=<sender|recipient|sender-domain|recipient-domain|global>
    --queue=<before-queue|before-local|before-remote|before-data>
    [ --mailname=<mailname> ]

This command removes the handler from the queue (defined by --queue) and leaves all the data associated with the handler in the database.

To enable a handler, run the following command:

# ./mail_handlers_control --enable
    --name=<handler name>
    --type=<sender|recipient|sender-domain|recipient-domain|global>
    --queue=<before-queue|before-local|before-remote|before-data>
    [ --mailname=<mailname> ]

This command adds the handler to the queue (defined in --queue) basing on the handler data remaining in the database.
