Forwarding email after twiddling with the headers

I have a situation where email is coming into an alias on my machine..

I need to identify that email, and add a couple of headers (one to prevent  
looping, the others to make sure the right people get it) and then mail it to  
a list of people.

I'm running into a few problems with what I've been using..

- It includes the original sender in the resent copy
- It is '>''ing the lines in the body of the message

Any help would be appreciated
