Requeue mails in Postfix

Postfix superintendent, postsuper, is the command to use for maintenance jobs on the queue.

With the option -r , messages are requeued. The message is moved to the maildrop queue and copied by the pickup daemon to a new queue file which will be subjected to address rewriting.

Since Phoo is still having problems, I needed to use this to redirect the mails that were already in the deferred queue at the backup MX, mail that had arrived before I had added an override redirect.
