I am also having the same problems. I hadn't noticed it until my queue
was over 30,000 messages. I haven't had the time to work out a real
solution yet. I didn't know if it was better to hack maildrop or hack
vdelivermail since I haven't even looked into either one of them yet.
What I had found was that one of my domains was receiving thousands of
messages per hour for non-existent users and bouncing back. So as a
quick fix, I set the default to delete, I shortened the queuelifetime to
3 days, and increased the concurrency settings because they were
constantly maxed out.
I'd also like to hear what real solutions people have come up with to
deal with this.
