SMPT Virtual Server Queue Stuck

I had an issue this morning with some emails being delivered and others
were not. I looked at the queue and one was stuck on a job from the 27th.
I froze this queue.

Question 1: How can I avoid finding this out "the hard way" in the future?

Question 2: How can I permanently delete the queue from the list vs. the
frozen mode?

Question 3: Is there a way to prioritize this queue, so I can make one
queue go ahead of another? Is it Force Connection?

Thanks ahead of time...
