value may be either a string or an integer, depending on the option's requirements.

The available options available:

DEBUG

This option determines whether a trace file is created for each autoreply. By default the value is 0 and this facility is off. A value of 1, creates an autoreply trace file for each autoreply sent in the IMTA's log directory. A value of 3 puts more information in the trace file.

RESEND_TIMEOUT

If mail arrives for a recipient with autoreply on, an autoreply is not sent if a certain period has not elapsed since the last autoreply was sent from this recipient to this specific sender. This option sets the time in hours, after which an autoreply is sent to the same sender again. The default value, if this option is not set, is 168 (for example, once a week).
