This is spoofed.

Code:

Received: from mail.vistomail.com (cpe-104-231-205-87.wi.res.rr.com
   [104.231.205.87])
   by smtp1.linuxfoundation.org (Postfix) with SMTP id 01BCADF

104.231.205.87 is not mail.vistomail.com. It's some residential IP, cpe-104-231-205-87.wi.res.rr.com.

I feel like the mailing list must be seriously misconfigured to allow this sort of spoofing... You could exploit this to send mail "from" any of the devs, for example.

I didn't check the headers, so I didn't notice this. That is very convincing that it is not Satoshi. But how can that domain name be spoofed? Does the sender set that name or is it done by the receiving server?
