CONSTANTS

       See README.plugins for hook specific information on applicable constants.

       Constants available:

       "OK"
           Return this only from the queue phase to indicate the mail was queued successfully.

       "DENY"
           Returning this from a hook causes a 5xx error (hard failure) to be returned to the
           connecting client.

       "DENYSOFT"
           Returning this from a hook causes a 4xx error (temporary failure - try again later) to
           be returned to the connecting client.

       "DECLINED"
           Returning this from a hook implies success, but tells qpsmtpd to go on to the next
           plugin.

       "DONE"
           Returning this from a hook implies success, but tells qpsmtpd to skip any remaining
           plugins for this phase.
