Thirdly ... I think it's ridiculous that Stanford's anti-spam rules
trawl through Received headers (which are defined as being free-form)
and look for suspicious hostnames when you've already sent that email
through your email provider and it has a valid DKIM header; gmail has
already certified that the email came from an authenticated user, why
does Stanford care what your local hostname is?
I suspect "Home IP address (in San Jose) sending via LHLD to gmail" from
it is just one factor in its ham/spam decision. Bob says with
"Received: from ayukawa" some are ham, but some are still spam. Perhaps
that means it made little difference.
Seems odd so much of Bob's mail to Stanford is considered spam. Wonder
what he's writing about. :-) Can Stanford recipients seems Bob's
emails in their spam folder and train Proofpoint that they're ham?
