Sign Clean Messages

[Spicer, Kevin]

Does anyone have a way of preventing mailscanner from signing clean messages which are in reply to messages signed previously?

The reason I ask is we use the sign clean messages function to add a disclaimer and where a conversation takes place by repeatedly replying to an email you end up with a chain of disclaimers at the end.  [I know this isn't what its intended for, so this isn't a bug just a side effect of my misuse!].
Unless anyone can suggest a better solution I'm thinking I might create a CustomConfig option which scans the body for a particular string in the disclaimer (maybe a line of -+-+-+ or something!) to decide whether to sign the message.  Does anyone know if/how the body can be accessed from CustomConfig?
