Put in the "hold" queue using "HOLD" in an access(5) table or header/body
checks. Release it with "postsuper -H" at your convenience.

        # Release all held mail, to be selective:
        # postsuper -H - < list_of_queue_ids_one_per_line
        #
        postsuper -H ALL

        # Optional if you can't wait for the next deferred queue scan:
        #
        postkick public qmgr D

I once had a "DELAY" patch for this, but it never quite panned out to
a feature that warranted inclusion in the official release.

If my response solves your problem, the best way to thank me is to not

"It worked, thanks" in the "Subject" so I can delete these quickly.
