Hector,

I know all about how I could publish SPF records.  You are missing my point.

In the previous message it was suggested that people who use a hosted DNS 
service should switch if their service doesn't support Type SPF.  The problem 
is that, as far as I'm aware, none of them do.  

I have not determined any source of economic motivation to get that to change.  
"Support this or I'll take my business to someone that does" is an empty 
threat unless someone actually does.  It's also not something anyone other 
than DNS purists would worry about.  No one is going to switch providers and 
risk downtime in order to publish a record that to a very, very close 
approximation accomplished nothing.
