Hi !!
You're missing the point of SPF. SPF allows a domain owner to publish
their policy. It doesn't guarantee that you'll like their policy.
well, spf was intended to stop email forgeries (among other things),
this particular use of spf does not stop email forgeries as any spammer
could hack a computer in this isp cable zone and start using all kind
of addresses of this domain (including the ones of the isp staff)
without any problem, well, it would be better as this forged emails will
be apparently be trusted by others as they are spf protected.
As I understand it from Nick Phillips's post above, BlueYonder's
current policy is that cable modem users are permitted to deliver mail
directly if they so choose. If that's the case then this SPF record
is a correct expression of their current policy.
true, but also a bad use of spf, of course you are free to buy a gun
and shoot yourself, but that's not a good thing
But surely SPF shouldn't be in the business of making value judgements
about policies; it's just a syntax for expressing them.
it's a tool to stop forgeries, but of course, it could be also be
used for ... well ... they should know
> If you don't
like BlueYonder's policies, then lobby them for change, or simply
don't accept mail from them.
yes, of course, we will not trust any email comming from them.

A little inaccuracy sometimes saves tons of explanation.
