As a practical matter, I must respectfully disagree. It will be some
time before everyone gets a chance to upgrade, and the timeout issue
with looking up SPF from some DNS server sets (not BIND or MS
implementations far as I can tell) is a significant issue. This timeout
issue could, of course, be a firewall issue... anyway, it has a
significant impact on high-volume (for various definitions of "high")
mail sites. And thus is ultimately off-topic for this list. FIN.
