Blueyonder is one of the two or three cable ISPs in the UK. Every
subscriber gets a blueyonder email address, but it's fine for
them to send directly.
i don't feel that this is ok, spf enabling all their cable users
They could do better, but this is a start. SPF is a tool that gives a
domain name owner the ability to assign credibility to e-mail sender
ip addresses etc. It does not say anything about the credibility of
the domain name owner...
If blueyonder doesn't implement additional measures to prevent
outgoing spam, SPF just prevents other ISPs from spamming using
blueyonder's e-mail addresses. This might remove some spam, which is
a step in the right direction.
Also remember, that SPF isn't just something you put at the smtp-port
on the receiving mail-server. It's also included in Spamassassin
2.7/3.0, and my guess is, that SPF really catches on when this comes.
Spam won't be killed overnight - people have to learn to use SPF, smtp
auth, port 25 filtering etc. first.
