Stop duplicate disclaimers on long reply threads

A legal disclaimer rule that simply appends text to every outgoing message works fine for a single email, but on a long back and forth thread the same disclaimer can end up stacked at the bottom three or four times as quoted history builds up underneath it.

MSH Postfix Milter avoids this with a built-in duplicate protector. Before a disclaimer is added, the application checks whether the message already contains it further down in the quoted text, and skips adding it again if it does.

Tuning the sensitivity

Different mail clients quote and reformat previous messages in slightly different ways, which can throw off a plain text match. Each disclaimer rule has a sensitivity level for duplicate detection, so if you notice the same disclaimer still slipping through more than once on a thread, lowering the sensitivity makes the match more forgiving and catches those reformatted copies too.

The result is threads that stay readable, with the disclaimer present exactly once no matter how many replies get added on top of it.
