Need a way to block delivery TO a site.
Two sites that have blocked us has resulted in 600,000+ messages to one and 700,000+ messages to the other backing up in queue, resulting in 150GB or so in our database. The security tab provides a method of blocking INCOMING, but does not provide a method of blocking OUTGOING to a site. Further there does not seem to be a way to select how long a message will remain in queue waiting to be delivered before it is discarded.
