IMHO, the largest deployment hurdle will be to get 63 million of
domain owners (growing at 1.5 million per month) to publish and
maintain a DNS record. (See my post at spf-discuss for source).
Presenting these non-technical people with the complexity of choosing
which scope their approved mail servers will be used and other complex
options we might provide them, seems to run counter to the 80/20 rule
for deployment.
A very small minority of those domains will do the actual publishing
themselves. They will rely on their vendors to publish for them and to
exchange the necessary information.
The average domain owner does not know what DNS is and if they do, they
have no idea who manages DNS for them. The record update problem is
serious and needs to be addressed within the industry, but the end user
education needs to take the form of telling people that (a) this exists
and (b) who to call.
Small business domains, of which there are literally millions,
generally outsource everything. If they are business to consumer they
may have an outsourced online shopping cart sending transaction
notices. They almost certainly have an ISP for business person to
person mail. And any email marketing will be a third provider.
The assumption that small domains all have simple configurations is
just not valid. It's probably true for small personal domains, and
small technical domains, but those are not the majority.
Failure to scope will make it harder, not easier, for small domains, if
for no other reason than figuring out what a rational receiver is
likely to do with the record will be that much harder for whoever is
doing the domain administration. This is currently a very low cost
service - do we want to make it expensive?
