Maybe the IETF Won't Publish SPF and Sender-ID as Experimental RFCs After All

[Fergie (Paul Ferguson)]

John Levine writes over on CircleID:

Yesterday, the IESG, the group that approves RFCs for publication received an appeal from Julian Mehnle to not to publish the Sender-ID spec as an experimental RFC due to technical defects. IESG members' responses were sympathetic to his concerns, so I'd say that a Sender-ID RFC has hit a roadblock.

The problem is simple: Although Sender-ID defines a new record type, called SPF 2.0, it also says that in the absence of a 2.0 record, it uses the older SPF1 record. Since SPF and Sender-ID can use the same records, if you publish an SPF record, you can't tell whether people are using it for SPF or Sender-ID.
