I took a look at the code and I think it's a race condition deleting a queue
file but I can't tell you where.

I use dma on a bunch of client systems and they never queue anything.
The queue file is created and deleted immediately as the mail goes out
to the smarthost. I could imagine that if you periodically run dma -q,
it could see a queue file which is then deleted by the time it tries
to do something with it.
