Well...
I have a hard time understanding all the text they wrote, but my
initial thought is that they granted everybody the right to use
their rfc 4408 without having to worry about microsoft's patents.
"...
Security Technologies
This promise applies to all existing versions of the following specifications:
[...]
RFC 4408 - Sender Policy Framework: Authorizing Use of Domains in “Mail
From�
[...]
"
So, not only do they abuse existing SPF records in an inappropriate,
incompatible way (by applying SPF records to RFC822 "From:"), now they
explicitly claim rights on rfc 4408.
I'm sure people will tell me if I see this the wrong way. Go ahead please.
There is, as I recall, some question about how broad their patent is. By
putting RFC 4408 on that list it means they promise not to sue people for
patent infringement if they implement RFC 4408. It says nothing about if they
actually have a relevant patent.
So, I think that putting 4408 on the list is good. It means they explicitly
promise not to sue SPF implementers. I don't think it means they claim any
ownership over SPF.
