way OT: add header (mailscanner) to be parsed by Outlook plugin for reporting false-negatives?

[am.lists]

What happens when something like this occurs:

1) I get a message to me through my hosted ESVA. It has that footer. I
know it's not spam, so I don't click it.
2) It's something important so I forward it to the wife, the
brother-in-law, etc.
3) They, not being as savvy, mistekenly click the link after it's left
my control.

As Andy says, it's not a perfect solution...
