I see what you're saying.  To be honest, when I added the SPF record, I 
was treating it only as a magic incantation to please Gmail. :)  It 
never seemed to help there, so maybe we should just remove it for now.

I'm sure no one has any such problem with what you've written.  It's a 
great benefit of the HCoop approach that all aspects of our architecture 
can be surprise-audited by all sorts of new and knowledgeable people. :)

I personally would even prefer it if you (and anyone else) left out bits 
of language like "only tentatively pointing out," any kind of apology, 
etc., so that messages are shorter and more to the point. ;)
