Sorry, I duplicated the VALID_LIST examples.

If a FROM “Name” is found in VALID_LIST[any] and does NOT match any line in VALID_LIST, then DENY.

I should not need to define all possible invalid email addresses for “CEO Smith”.  No AI or Bayes algorithm is needed.
* Example Invalid:  "CEO Smith" <anything.else at>

For small organizations with a limited number of people, including outside contacts, it should not be difficult to implement and avoid a large number of impersonation attacks.
