Therefore I think we should adopt Scott Kitterman's proposal:

Wayne, what do you think?

I think that "accepts responsibility" is a loaded term that will scare
away people from publishing SPF records.  Does that mean that the
domain owner must accept all responsiblity for any illegal, immoral or
unethical behavior that the MTA owner and/or user of that MTA may do?

Do you want to try and add a paragraph and a half qualifying just what
kinds of responsiblities the domain owner is accepting?

Is this kind of responsibility something that current SPF publishers
have already accepted?  If not, should we retroactively foist such
responsibility on them?


As much as I might like to increase the accountability of MTA owners,
I think this is a *REALLY* bad idea.   I confess that I didn't
initially see it this way, but it is something that, thinking about
it, just started to bug me.

I didn't mean it to be anything other than a clarification of the current 
situation.

Is ...is accountable... any better than ...accepts responsibility...  All 
I'm trying to capture is the idea that if an MTA that I give a pass to 
sends out bad mail with my name on it, I shouldn't whine if that name ends 
up on an RBL or my reputation suffers.  So, before I give a pass, I better 
trust the MTA for real.

I don't think this is news.  The domain based RBL example's been on the 
spf.pobox.com site for a year.
