Frankly I've found this restrict_post to be completely useless 
(unfortunately).  Not because of the way it's designed.  It makes sense
but it doesn't work in my case because a huge majority of the subscribers
send mail from addresses that are definitely not in the list of subscribers.
You might at first tell me to force them to subscribe one address and use
only that address...easier said than done...when many of them have From
addresses in their headers they've never even heard of and if you send mail
back to some of these From addresses they'll never get that mail.  People's
"real" email addresses and the email addresses their site admins have put
in the headers (or more accurately didn't not put in the headers) are too
often so different that I can't use the restrict_post option.

This is unfortunate but I don't know a way around.

Mike
