The vcap-dev list used to use a Reply-To header pointing back to the list such that replying to a post would automatically go back to the list. The current mailman configuration for cf-dev does not set a Reply-To header and the default behavior is to reply to the author.
While I understand the pros and cons of setting the Reply-To header, this new behavior has bitten me several times and I've found myself re-posting a response to the list instead of just the author.
I'm interested in knowing if anyone else has been bitten by this behavior and would like a Reply-To header added back...
