Domain SPF Records

Was looking at a couple of domains at dnsreport.com today and noticed
highlighting because of a missing SPF record that is supposed to be in place
by October 1, 2004.

Apparently SPF = Sender Policy Framework.
It's a DNS record to allow SMTP receivers to verify envelope sender address,
and can distinguish legitimate mail from spam before any message data is
transmitted

There was a link to http://spf.pobox.com/index.html

How serious is this requirement? Only found RFC references to OSPF, nothing
to SPF.

That is because it is still only a draft. there are two othe options being
considered at the same time, RMX and DMP, only one of which will be
recommended.

Once adopted, (SPF seems the most likely at this time because of support),
its importance will be determined by the number of servers that adopt it.
E.g. if it is adopted by the larger ISPs any mail server not using it may
find it difficult to send mail to clients of those ISPs. - could be a case
of use it, just in case:-)

That is the date that Hotmail say they will enforce SPF. If your domain's
mail server does not include SPF, you will not be able to email @hotmail
users.

AOL, Earthlink, GMail, and others are also behind the SPF standard.

Here is a little wizard that helps you create an SPF record of your domain
(s).

Here is the Slashdot article that mentions the Oct. 1 deadline.

I have been told that if an incoming email doesn't have an spf record, many
hosts will still pass it to an RBL check and if it passes that, allow it to
go through. I was not able to get a confirming citation/link for that info
and it doesn't make sense to me.

Is spf checking going to be a problem for domains on a shared ip using
localhost for smtp service?
