do you think I care of the specs if "important" implementations go west?
If you exclude broken specs and implementations, I will say that I have

to sum it up: I don't see what spf would bring to me. the only time I
tried it, it went against me. that's enough for me. all other stuff is
pure theory compared to what I've seen. that's it. nothing more, nothing
less. and yes, I am biased. I was already convinced that spf was wrong
and I decided to give it a chance. the result was that I now know that
it is not even "neutral".
if you like spf, that's good for you. I don't. and it doesn't help to
believe that those who don't believe in are mistaken and have "false
assumptions". This is not acceptable. I respect opinions of those who
accept other people's opinions.
this subject has been debated many many times in many many places. let's
