In case anyone would like to read the new senderid draft - it's at
http://www.spfhelp.com/downloads/draft-lyon-senderid-core-00.txt
I found a mistake in this draft:
In section "3.4 Backward Compatibility" it says:
In order to provide backward compatibility for these domains, Sender ID
implementations SHOULD interpret the version prefix "v=spf1" as equivalent
to "spf2.0/mfrom,pra", provided no record starting with "spf2.0" exists.
But correct is:
In order to provide backward compatibility for these domains, Sender ID
implementations MUST interpret the version prefix "v=spf1" as equivalent to
"spf2.0/mfrom", provided no record starting with "spf2.0" exists.
