And remember to do the world a favor and un-do that change when the immediate
problem is past. :)

Another good way to avoid annoyed replies is to not have disclaimers longer than
the actual posting.  My favorite:

"... if you are not an intended recipient, you must not copy, distribute or
take any action in reliance on it."

Do you have any legal citations to justify a "must" as opposed to a "pretty please
with sugar on it"?

"If this message is being transmitted over the Internet, be aware that it may
be intercepted by third parties." and pick something.  It's more
effective than a disclaimer.
