Which sort of splits the spf community in two halves, those using http lookups
and those that do not. Better stick to a uniform policy. The basic idea is
that, given time, TXT records will be standard for every dns hoster. Es
Not really, it rather forces those who are serious about using
SPF to do the http lookups. There are actually serveral distinct
problems with it, but the key one is it is an unnecessary duplication
of information. As such it complicates setup and increases the odds for
problems both in setup and in operations.
As far as the problem with domains that do not have access to their own
DNS record to add TXT records, I believe that it will become a self
resolving problem if SPF takeup passes 10% of domains, as the nameserver
operators will see the need themselves.
Yes, it does mean that some people who would like to publish SPF now
can't, but that is a lesser problem than crippling the protocol with
unneeded complexity would be, and one that will be solved in time.
