Replies to auto-forwarded email.

[BadFish523]

I have a couple emails setup to be auto forwarded to a group of people. It is setup to auto forward to the group when the subject contains specific words. At the top of the email it says do not reply to this message but some people still do. When they reply to the message the reply still has those same specific words so it them auto forwards the reply to everyone again. So they get the reply then the get the reply as an auto forwarded message from me again. I looked in the exceptions and can't think of a way to stop this. Unless you guys think putting in an exception that has the specific words in the subject but with the RE at the beginning? Any help? Thanks.
