Description

This hook is called to schedule a mail queue maintainer for a mail queue. The default implementation will cancel the maintainer if the queue is empty, else if there are messages in the active queue it will schedule for now + delayed_queue_scan_interval, else (delayed messages only) it will schedule for the next attempt time of the first delayed message or now + delayed_queue_scan_interval, whichever is sooner. You can override this behavior by registering this hook and returning nonzero when you are done; returning 0 will cause the default implementation to run. To cancel an existing maintainer event, you may call mail_queue_stop_maintainer. When creating a mailtainer, the timed event worker must be mail_queue_maintainer, and the closure must be the domain name, which you allocate as a MEMTYPE_STRING. now may be NULL, in which case you should call get_now to get the time.
