Interesting, the (relatively) "new" processing limits cause no
significant problems.  The "bad includes" probably include bad
redirections, that's tough.

Thee appeared to be no bad redirect: anywhere


If that was a list with 6000 problems, was each record counted
once, or once per mail ?

Once per domain.


And what's the number of "no problem"
in relation to 6000 ?

I'm not sure how long the list took to build, but from memory he handles about 100,000 mails a day.


We probably need something like this for
a "lessons learned" + "implementation interoperability report"
(or whatever the name is) later when SPF is updated to PS.  Bye

Yep - and he has had significant results from his efforts to contact people and get spf records fixed.
