New topic. Need a procmail recipe.

[Steven W. Orr]

I have two mailinglists. Let's call them A and B. All members of A are 
allowed to be zubzcribed to B. Not all members of B are allowed to be 
zubzcribed to A. Noone is allowed to post to either list unless they are 
zubzcribed to that list.

I want people on A to not be allowed to send a single message to both A 
and B. If someone sends to both A and B it should hit procmail and 
automagically be send only to B.

[If someone on B sends to A and B, that would automatically block the 
message to A.]

So the recap is this:
An A person sends to A. S'right
An A person sends to B. Also S'right.
An A person who is not zub'd to B sends to both A and B. His message to
would be blocked.
I just want a message send by an A person to both A and B to only go to B.

Anyone? Please?
