What "SPF record type"?
Using the tools at http://www.openspf.org/ produces the TXT record, and
I don't find any mention to SPF records, on the other hand it says "The
specification has been frozen" talking about the TXT record.
After many complaints from the DNS community over SPF "hijacking" the
TXT record, a new SPF record type was eventually accepted. Modern DNS
servers allow you to create the record as type SPF to avoid the
hijacking. However, as implied earlier in this thread, there may still
exist software that doesn't yet support the new record type in addition
to DNS administrators that don't realize they have the option. If
you're not already using the TXT record for something else, you should
consider publishing both.
From http://www.openspf.org/FAQ/TXT_abuse, "Currently almost all SPF
records are published only as type TXT. Type SPF records (Type99) should
be published if DNS servers are capable of it, but MUST be identical."
