Sender Policy Framework

Are many (all ?) v2.listbox mailing lists gone? Or do they block gmail? So far my attempts to read the announce - council - webmasters lists failed, and new subscriptions also failed. The real problem: I lost my password for this wiki, and the procedure to ask on the webmasters list for help does not work without a webmasters list... ;-)

Notes for later:

GMail about SPF and DKIM (2011)

Google Research: The war against spam (2011, PDF)

IIJ review vol. 9 (2010, PDF): slight decrease in SPF deployment, but 4.4% FAIL

DNS Survey (2010, PDF): 66% EDNS0, 16% SPF, 0.01% SenderID, 2.5% DKIM
