right now SPF tells you to publish an SPF record for every single
subdomain that has either A or MX. but that's yucky.
but if we add a match_subdomains modifier to domain.com's record, we
can allow subdomain lookups and the problem is solved!
what do people think?
domain.com IN TXT "v=spf1 -all match_subdomains=1"

switched to -all.
