Yes, section 4.7 of Mark's draft contains an example of a valid domain name
which is an invalid host name:
v=spf1 +mx redirect=_spf.example.com
So why should following not be allowed?
v=spf1 +mx redirect=/spf.example.com
BTW. My latest SPF implementation (v1.9) supports Mark's syntax, Wayne's
syntax and the "%!" macro.
