Conditional rule based on content information

It's in the latest releases. Here's the relevant chunk from 

# This option can be used to stop any duplication of en email signature
# appearing in the HTML of an email message. It looks for the "alt"
# attribute in the <img> tag specifying the image to be inserted int the
# HTML signature. If you want to use this option without inserting an image
# into the signature, simply specify an <img> tag without a "src" attribute.
# If the "alt" tag appears, and contains the word "MailScanner" and the
# word "Signature" and the %org-name% you specified at the top of this file,
# then the message is considered to already be signed. If this option is
# also set to "yes", then it will not be signed again. Multiple image
# signatures at the bottom of a message can make the message very large and
# ugly once it has been replied to a couple of times.
# This can also be the filename of a ruleset.
Allow Multiple HTML Signatures = no

This should do exactly what you're looking for. If it doesn't then let 
me know and I'll see what adjustments can be made.
