Re: Updating SPF type99 and TXT RR's: Simultaneity is not guaranteed.

* Scott Kitterman:

The key point from your paragraph is, "Starting with the set of records that
were returned by the lookup".  During the lookup you don't have to look at
both.  If you do, you have to PermError.

Okay, thanks.  This means that the receiver has some freedom.  As a
publisher of an SPF record, I have to assume that it exercises this
freedom.  Unless the requirement I quoted is dropped, I still have to
temporarily remove SPF records (or TXT records, or both) to
unambiguously express *my* policy (after all, it's the *Sender* Policy
Framework).  A temporary PermError is probably *not* what I want.
