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?
I like it but what happens if I want to do both mailfrom and pra, would
I publish two records?
Does this also increase a chance for collisions perhaps needing a prefix?
If the scope of a Sender-ID record could be used to signify many things,
does that mean that beside mailfrom and pra, other extensions are
possible in the future? Would that require an IANA registry?
