Qmail Destroy is a program to remove a message from qmail's queue. Its main benefit is you do not have to temporarily stop qmail to use it. You can remove messages from an active mail queue.
To do this, Qmail Destroy flags each recipient as though qmail completed the delivery to them. After seeing this, qmail will clean the message up and not deliver it any further.
Warning: The messages you remove using Qmail Destroy will be permanently lost.
Qmail Destroy is free software and we release it under the GPLv3 license.
