When the messages do go out, whichever moderator we designate the message go out from, then gets all 16,000+ messages in their sent box. And theres no way to bulk delete aside from going into the database and deleting them there. If we don't bulk delete, then it freezes up the moderator's mailbox and causes random glitches in various users' mailboxes, where they cannot access their mailbox or just their sent box.

Is there a way to make it so the messages do NOT go into the moderator's sent box?? So that this doesnt clog up the database.

We have used this plugin on smaller sites (maybe 6000 members and we dont have this kind of extreme problem) but all the messages still get sent into the sent box of the moderator.

Thx!
