Hi, <http://spf-all.com/stats.html> is quite fascinating,
it says that over 99.95% of about 2,500,000 evaluated SPF
records use no macros at all. Of course this can't tell
us how much FAIL-protected mails desperately need macros.
Most things macros can do, a machine generated zonefile (static
or dynamic) can do as well or better. Macros mainly give the policy
access to localpart and helo (both of which are more likely to tickle
SPF implementation bugs due to their unconstrained evilness).
