We are receiving way too many errors to monitor on our list.  Our list has 
under 100 subscribers and is very quiet most of the time, yet we receive 
error monitoring for up to 300 bounces a day.  I realize that all or almost 
all are from people who aren't subscribed.

Is there anything I can put in the header to cut down on this so that we 
can properly keep track of our subscribers?
