| Stupid question perhaps, but how will it handle this case:
| example.com enables watermarking using MailScanner
| userA has emailaddress userA at example.com
| On his homepc he configures his mail program to use userA at example.com as
| the From adress.
| When he sends mail from home he uses his ISP smarthost and not the
| mailsystem at example.com
| What happens when mail sent this way is bounced somewhere on the way?

It will be dumped. The problem is that you shouldn't allow people to do
this to begin with. People may think it is not flexible but it is that
darn "I don't care if is wrong just do it"mentality that is allow so
much spam.
