Re: Blacklists - URL and IP

Interesting... it would seem that Hotmail & MSN soon plan on marking all
email from domains without SPF / Sender ID records as SPAM.

While it's clearly debatable whether or not to use SPF checks against your
incoming email, it is probably at least worth creating the simple DNS record
for your domain(s) just in case.  Personally, I don't think they will be
successful in demanding this requirement so quickly, if ever.

The problem that SPF solves is that it helps stop people spoofing your
domain, as long as the recipient checks SPF.  It doesn't stop spam because
the spammers create valid SPF records for their own numerous domains, which
they change regularly because they have some of the more dubious registrars
in their pockets.
