Lucian -

Oddly, I'm not receiving your messages sent to this list... perhaps
we're running into the dreaded list/forward corner case.  Anyway, I'm
only able to see the replies from Franck and Tim... so I've only seen
what they've included in their replies.

Anyway, wearing my "PayPal" hat (emblazoned with a fancy "Ecosystem
Security" logo)...

Yes, PayPal knows about the issue you've identified.   In fact, you're
seeing in the feedback reports exactly the reason that we started
working on DMARC.  Spoofing used to be a common method to sent mail, but
we learned that it leaves holes open for abuse.

Fortunately, those holes are being closed in a series of rolling
updates.  It'll be a couple months before it's fully deployed to all
business units and mail streams around the world.  As you can imagine
with a system as complex as PayPal's, it's not as easy as changing a
lightbulb.

Hope this helps... and thanks for the report.
