Satoshi email analysis
Here's a quick technical analysis of the email sent to the bitcoin-dev mailing list today at http://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-August/010238.html
The email was sent from an anonymous email provider called vistomail.com which gives the appearance of being out of service. However you can see the logins at https://webmail.vistomail.com/
The vistomail servers are authorised to originate email by their IP address via the SPF DNS records . Satoshi used satoshi@vistomail.com when first announcing Bitcoin http://www.metzdowd.com/pipermail/cryptography/2009-January/014994.html
From this you can safely conclude the email did originate from vistomail.com servers and was not spoofed. It does not prove the account was not hacked of course.
