Which means *everyone* except for very very small closed groups, has to
use softfail policy - ebay, amazon, the banks etc etc because they don't
have control of what legitimate recipients do with their mail.
So its absolutely zero use at all. Its broken. Its dead. Only the
idiots care about SPF any more.
Talking about SPF is not just beating a dead horse, the thing has been
pulped into nothingness and then fossilised.
So can we just drop the whole thing on this list before I start
expressing my real opinion on the matter and having to put a BBFC rating
on the list....
