queue backup

[Jay Moore]

I have qmail/ezmlm-idx.  We are serving over 100 mailing lists with a 
total of about 50,000 subscribers.  The output from qmail-qstat is:

messages in queue: 2293
messages in queue but not yet preprocessed: 0

My first question is how to I purge the queue.  

The second question is what causes the queue to hold these messages.


The queue size seems to continue grow it never comes down.  We are not 
having any complaints from our subscribers at all.

Thanx,
Jay
