OOPs forgot one criteria,
* There is no valid signature
:-)
I think that there will be a lot of value in the 'no I mean it' modifier in the
next couple of years. Eventually I hope we can fix the relays and everyone can
mean it.
Another semantic difference is that if I see someone claiming to be a target of
phishing and I see fake messages I am likely to want to report them.

Mostly +1
But there could be utility in the sender saying 'My email
is at very
serious risk of being impersonated'.
What is that utility? Please expand on what behaviour you
expect from
the recipient and how that will differ from the case where
the sender
does not say that.
If I know that you are a self declared target of phishing
and that the
consequences of letting a phish go through are considerably more
serious than a random impersonation spam I can adjust my
spam filters
accordingly.
In particular I would expect to filter out ALL mail
automatically in
the case that ALL the following apply:
* The sender ALWAYS signs
* The sender declares themselves to be at risk of phishing attack
* The content is HTML
* There are URIs in the body of the text message
* The message has not been forwarded by a previously noted
intermediary.
How does that differ from the case where:
* The sender ALWAYS signs
* The content is HTML
* There are URIs in the body of the text message
* The message has not been forwarded by a previously noted
intermediary.
I guess that the real question is what's the difference
between "I always sign"
and "I always sign and I get phished"?
The impression I'm getting, from several people, is that "I
always sign" is already being written off as likely to be
ignored by recipients and that there needs to be a "No, I
really mean it!" modifier?
Cheers,
Steve
