Can you modify the Resolution email with a "do not reply" message?

Hi all,
 
We try to be nice, and ensure our resolution emails have friendly comments.
One of the techs in my team says this encourages people to reply back and say thanks, which then re-opens the case.
 
Can we put a message "please do not reply to this message" on the bottom of each email, without needing to use a resoution template?
