[CentOS] Another Postfix (or procmail ??) question

Is there a simple way to strip out what I assume is a header that asks 
for a receipt that the message was delivered?

I never like to send such receipts, and they are annoying.

It mostly happens on a couple lists I'm on (not this one) - I don't just 
want it for myself, I may be setting up a list soon and if soon, would 
want to strip such requests out of the message before the list server 
sends it to the list.
