MJ,
I was notified of your question because I had asked the same question a number of years ago. To answer your question, no this issue has not yet been resolved by Intuit--and this includes the recent response you got from Adrian.
While the Intuit recommended include statement "include:intuit.com" is syntactically valid, it results in a recursive parsing error that exceeds most mail servers ability to validate an SPF record (including Google's). I just tried to add this reference back into my DNS record and it failed again.
The SPF string can not be parsed, do you have any typos in it?
| Decision | permanent error in processing |
| Explanation | SPF Permanent Error: Too many DNS lookups |
| Record | v=spf1 +a +mx +ip4:##.##.##.## +include:_spf.google.com +include:intuit.com +include:servers.#### +include:email.#### ~all |
(Other records have been obfuscated for my domain)
To see how this SPF record parses, you can visit: www.spf-record.com/spf-lookup/intuit.com and see the huge number of IP numbers and external references that this include statement parses to.
So until Intuit hires someone who knows about modern email validation and authentication rules, the only option is to not use SPF validation for your outgoing invoices. (And let's not even start to talk about DKIM authentication for outgoing invoices).
