This plugin adds a configurable signature to every outgoing email that WordPress sends
This probably means that the plugin sending the mail is using its own mechanism to send it, instead of calling wp_mail as it should. Request the plugin author to instead use WordPress's official mechanism.
That's right. If you have some code that's capable of delving inside the HTML to do this correctly, then I'll be pleased to use it. But I couldn't think of a way.
