I just tried http://senderid.espcoalition.org/ and I was wondering if what they are doing is correct:

MAIL FROM: craig(_at_)spam(_dot_)co(_dot_)nz
PRA: craig(_at_)spam(_dot_)co(_dot_)nz
SPF-Record-Classic: v=spf1 ip4:219.88.242.0/27 -all
SPF-Record-MFROM Scope: v=spf1 ip4:219.88.242.0/27 -all
SPF-Record-PRA Scope: spf2.0/pra ip4:219.88.242.0/27 -all
SPF-Method Result: pass(spam.co.nz: domain of spam.co.nz designates 219.88.242.3 as permitted sender) SenderID-MFROM-Method Result: pass(spam.co.nz: domain of spam.co.nz designates 219.88.242.3 as permitted sender) SenderID-PRA-Method Result: pass(spam.co.nz: domain of spam.co.nz designates 219.88.242.3 as permitted sender)
DomainKey-Status: bad format: No DomainKey signature found

They are testing for MFROM and PRA for SenderID. but using the v=spf1 record for the SPF-MFROM test As I only put a spf2.0/pra it should NOT check for the SenderID MFROM at all.

Am I correct?

Also they say (maybe incorrectly)
Senders should publish SPF-Records in version 1 or version 2 formats, not both. The version 2 format was designed for senders who use different domains in their PRA and MAIL FROM headers, or senders who do not wish to define a policy for the SenderID-PRA-Method. Most senders use the same domains in both and therefore should publish SPF-Records in version 1 format only. Using version 2 of the SPF-Records, a sender can specify whether the record provides information about domains found in the MAIL FROM (MFROM) header (scope), the PRA header (scope) or both. Senders may publish one SPF version 2 record for each scope.

Thanks
