Okay, looks like the queue runner is using the right queue - which is why your mail isn't going out - so either Mailscanner is causing it to end up in the wrong queue, or the incoming sendmail is queueing in the wrong place

And sendmail seems to have the correct queue in the cf file

Seems reasonable

So it looks like incoming mail is going into clientmqueue not mqueue.in.  I'd check your init script to make sure its set to use the correct queue.  Are you sure this is all mail (incoming and outgoing), or just mail sent from the machine hosting the mailscanner?

It might be informative to take a look at some of the headers in the qf files to see whats happening.
