You are correct. In fact, HOTMAIL will today bounce those
messages. SPF is already implemented there.

That's all it does.
Well, I fear that that may be problematic enough.
So let's say you send email for ringlink.com through your ISP's SMTP
server. You just note that in the SPF entry in the zone file. If you
also send it through, say, your own SMTP service on your web server,
you simple add the IP address of the web server to the SPF
record. If
you used everyone.net's system to send, you would add that
to the SPF
record.
It's simply a way to tell the receiving server who may send
email for
a domain.
Let me try to explain my concern with an example:
Assume that I was running a Ringlink ring at
http://www.ring-master.com/ Furthermore, assume that I had an
AOL email address registered as the ringmaster address of
that ring. Then, for the case that ring-master.com is not
included in AOL's SPF record ;-), and if I have understood
this correctly, the email notifications from Ringlink to
those members might be bounced.
Please correct me if I'm wrong. I'd like to be wrong.
