spf2.0

I have been looking around, but it seems I cannot find a TXT record that has spf2.0 they are all v=spf1

This seems strange to me. I know that SPF is part of SenderID but then... So is SenderID really deployed or it is just SPF?

ebay.com and paypal.com are the two I can think of (though paypal.com  
seem to have broken their DNS a little right now).

SenderID is dead. The only group that every liked it was Microsoft /  
Hotmail, and even they don't publish it. Any records you see are  
mostly just fossil relics of an earlier era.

And one SenderID/SPF issue that you *will* run into is that...

The Sender ID spec tells you that if you see a v=spf1 record, you should
treat it as though it were spf2.0/mfrom,pra when, in fact, if *should*
be treated as though it were spf2.0/mfrom.  any assumption of "pra" is
not necessarily a valid read of the sending domains wishes.

And you have to submit your SPF record to MS CIDF database otherwise MS does not even read it from the DNS. Is that a joke?

Yes senderID is truly dead.

that is why we use spf2.0/pra records for our clients (in addition to
v=spf1 records). So I think as long as MS abuses v=spf1 records,
SenderID lives....
