It is the opinion of the co-chairs at this time (before the end of last
call) that the MARID working group has no consensus regarding the
deployment of Sender ID. This lack of consensus centers around the IPR
associated with the PRA algorithm. Since predicting deployment is a
subjective matter and not strictly a technical concern, we would like
to offer the working group a proposal for modifying Sender ID that
would take the issue of deployment out of the hands of the IETF and
place it in the hands of the ultimate decision-makers, the systems and
network administrators of the Internet. We feel that this is where
decisions of deployment should really be made.
It is also the opinion of the co-chairs that many in the working group
are willing to deploy MAIL FROM checking as specified in
draft-mengwong-spf. Therefore, we ask for consideration of the
following proposal:
The ABNF in -protocol 3.4.1 is (mostly from a post by Wayne)
version = "spf2." ver-minor "/" ver-scope *( "," ver-scope )
ver-minor = 1*DIGIT
ver-scope = "pra" / "mailfrom" / name
name = alpha *( alpha / digit / "-" / "_" / "." )
And the following stipulations:
1) "mailfrom" checking will be defined in a new draft
2) multiple records are allowed
3) a scope (e.g. "pra") can only appear in one record of one type for
validity purposes
The question before the working group: assuming no technical errors
with the above, is there anybody who vehemently objects with this
proposal?
