temporarily reply with all headers

[Erika Pacholleck]

I need an advice how I would best do this:

0. default is: take all headers out
1. for a mailinglist reply to mailinglist [EMAIL PROTECTED]
-. put all headers in the beginning
-. then reply blahblah

I need this only in some very special cases to track some bouncing
which should not occur. So I would like not to do any big changes
in my rc files.
Any suggestions how to accomplish that best? Thanks.
