Today I received an email from satoshin@gmx.com (Satoshi's old email address), the contents of which make me almost certain that the email account is compromised. The email was not spoofed in any way. It seems very likely that either Satoshi's email account in particular or gmx.com in general was compromised, and the email account is now under the control of someone else. Perhaps satoshin@gmx.com expired and then someone else registered it.

Don't trust any email sent from satoshin@gmx.com unless it is signed by Satoshi. (Everyone should have done this even without my warning, of course.)

I wonder when the email was compromised, and whether it could have been used to make the post on p2pfoundation.ning.com. (Edit: I was referring here to the Dorian Nakamoto post. After I posted this, there was another p2pfoundation.ning.com post.)
