Not really: http://new.openspf.org/SPF_vs_Sender_ID

However "widely deployed" is defined.
It is more widely deployed than any remotely similar proposed mechanism
(including and especially SenderId - which addresses actually another
problem).

It works if it is used correctly (as any tool in the world).
The "problem" is that postmasters on the Net must do something (namely
1) define if they want to allow others to detect forged emails claimed
to come from their domain and 2) - if yes to 1) - to get appropriate SPF
records into DNS) and people must either use a "good" mail relay (and
not just the one next door) or convince postmasters to change the SPF
records.

As you see, standards change.

> Do you really want that?

Yes. Especially gmail.com should do such a thing - there is such a lot
of - presumbly forged - @gmail.com mails in my mailboxes that
blacklisting the whole domain causes probably more good than bad (for
me, of course).
