It's not, and the supposed name is 'cooper' in my copy.

It was apparently sent via MailChimp (apparently now an Intuit company?) 
to everyone on this mailing list. e.g. it was sent to the unique address 
I use for this list.

It also looks like a confirmation pass by a spammer who wants to look 
legit.

Not a lot, which is likely because I have custom local rules and score 
adjustments which result in rejection of most MC mail, including ALL of 
their garbage not sent to a tagged address.

Seems like the right choice.

You may wish to weaken the IADB "OPTIN" and "VOUCHED" rules, as they 
really are not very accurate.
