To what hosting company should I switch if I want to publish SPF records of
Type SPF?
SMTP hosting systems are not stuck using their ISP's primary name
servers currently limited in their customer's UI management of
domain(s) zone file(s).
You could always use your own name server or use another that is more
flexible. No need to switch ISPs. Some may even allow you to do
offline editing (export/import) of your zone files.
If you don't wish to have your own primary DNS server, there are many
out there you can switch to, some even free, and perhaps for only
using a faster, more 24x7 reliable name server than their ISP's name
servers who could be tier limiting the customer.
I've gone through this issue a # of times just with SRV with customers
and their ISPs was limited in the UI in some way. Not an issue today
with SRV, but the idea of installing or switching the name servers
was always a last recourse option considered.
Yet, even if the ISP or with your own name server you added the SPF
type, that still didn't mean all query paths taken would be
successful. It could work 100% with testing short distance paths and
locally, but from a remote different path? It may not work. That was
the early RFC3597 issues I experienced that basically made you just
punt of the idea of using new RR type with the obvious overhead waste.
But my experience today, the RFC3597 issues are much less. I would
not hesitate to finally enabling SPF type as a default option in our
wares, at least give a new look for reasonable feasible results on par
with the migration that has materialized.
