Is there a small app thats available to do reports on a SMTP queue?
This is a IIS queue, not Exchange

I created a small script that monitors the number of messsages in the queue and sends out a notice when it gets too big.. but now I want to know where the problem messages are trying to go.

I'm gonna write up something quick, but it'd be nice to have a full app that can give me more information.

Any ideas?
