By the way. Since SPF2/PRA records share the same packet space with the
SPF1, we will definately have problems. One of these two MUST move to
their own hostname. For instance _spf.{domain_name} or _spf2.{domain_name}.
Since there are more spf1 records than spf2 records currently published,
it will probably be PRA that must move.
The move could be done in a backwards compatible way:
If the {domainname} TXT query did not return a PRA record, but did
return an SPF1 record, try looking at _spf2.{domain_name}
else
There is no PRA record, don't do the extra query.
We should bring this up to the PRA people before they get too close to
the point of no-changes-acceptable.
The PRA people are at Microsoft. You can search the MXCOMP archives if you
want to know who.
That's also a source of historical information on the political and technical
history between
SPF and Caller-ID/Sender ID. If you aren't well versed in that history (I'm
not saying you
aren't, just if), I recommend you read up before you even consider
contacting them. Much of this has also been discussed on spf-discuss.
