Email scan notice

Using OSX 10.8.2 and Outlook for Mac 2011 - Sorry if this is repetitious, saw question asked but didn’t see an answer.
Is there a way to foot email messages (similar to AVG) indicating sent email has been scanned by aVast, along with def. version? I realize its not “fool-proof” but offers recipients some assurance that one is trying to be a good citizen. Thank you.
