Re: Fwd: [marf] I-D Action: draft-ietf-marf-spf-reporting-00.txt

You can do most of this today by careful choice of the elements in your 
SPF record.

My SPF record contains a logging entry that allows me to see who is 
sending mail for my domain. This, coupled with a 'stunt' DNS server 
allows me to create logs showing what is going on.

Yes, this proposal is more versatile, but I have to question the premise:

The last sentence isn't true -- I'm doing it today. However, I will 
admit that there are buggy implementations of SPF that don't get all the 
macro expansions correct! Adding a new mechanism is unlikely to help this.

My record is (currently):

v=spf1
ip4:140.177.205.131
a:mail.employees.org
ip6:2001:1868:4001:3a00:21:9bff:fefc:5ac9
-exists:%{i}.%{l1r-}.user.%{d}
ptr:zen.co.uk
a:charon.gladstonefamily.net
-exists:%{ir}.mrbl.%{d}
-exists:%{i}.3/86400.rate.%{d}
~all

p.s. Would people be interested in a web interface to look at their SPF 
drop statistics?
