Display a possible fraud warning

[Chris_Ray]

If an email arrives from an address NOT in my contact list, but using a Display Name that IS in my contact list. Raise a WARNING.

It could be that the person has changed email provider.  But it could be a scammer setting up an email account similar to someone I know using the SAME Display Name.

Just had a scammer asking for £300 of amazon gift cards using this exact trick. I replied thinking it was my friend, but bad grammar in their reply led me to check the actual email address which was NOT my friend's.

Lucky escape, but identified this possible improvement.
