I've got two of them,one to my Gmail addy which I have never used with my Paypal account because there was NO Gmail when I set up the Paypal account.Gmail picked it out a a suspect phishing exercise and invite me to report it which I did.Excellent service at Gmail.
Yesterday I got one with details of my expired card at Paypal to my old NTL addy which I sent to
spoof@paypal.com to be told it was real .Last week I sent another to spoof@paypal which was fake.It is going to affect peoples confidence in certain sites and services I'm afraid.
Cloudmarks Safety bar treated this one as Spam so I guess they have sent out too many of them and the Cloudmark community have considered them spam too.
Frankly I'm more than glad to abandon Paypal after reading some of the online info about them.I never used it more than twice anyway.Same goes for Ebay.

I no longer trust them either.
