In article <3423731.dTAWf75mkY@linux-9daj> you write:

i briefly considered adding such a record until i found that only one TXT
string is permitted, so TXT "v=spf1 mx" not TXT (v=spf1 mx) in the zone file.
Nope. You can have as many strings as you want. They're treated as
though they were one catenated string. This is a concession to
provisioning crudware that doesn't handle multi-string TXT records
very well. (Those I agree are often ignorant.)
in that case, i'll try it.
i guess i'll just add one with "v=spf1 +all" to shut google up?
It is rarely a good idea to assume that the people to whom you are
sending your mail are stupid. Your SPF of "mx ~all" is fine.
so many ignorant and poor judgements shaping this future.
You can certainly disagree with Google's choices here, but they had
their reasons and it's not because they're ignorant. What is
convenient for those of us with individual or SME mail systems doesn't
scale very well to systems that have to defend against billions of
spam messages every day.
not going to argue that here.
