Re: [spf-discuss] Does anyone actually filter by spf records?

I set up a spf record for my domain. I tested my text record out on
http://www.seoconsultants.com/tools/spf/ . text record seems to work
fine. FYI, this is what it is, real simple:
v=spf1 ip4:64.79.160.23  -all

However, when I send an email from an unrelated ip address (should
return a hard fail), it still happily gets accepted by Yahoo, Hotmail,
gmail, and aol. These emails should not even return in the email box?
What gives? I know these domains have spf records, but I am not sure if
their email servers actually CHECK other people's spf records and
filters by the rules of spf.

Anyone knows what's going on?

YAHOO.COM does not support SPF.

AOL.COM has an SPF policy but I don't think they support SPF at the server.

HOTMAIL.COM is suppose to be supporting SPF via SPF 2.0 AKA SENDER-ID/PRA

GMAIL.COM does SPF checks, it seems, but it might be passing the results to
the users.

To answer your question, YES, there are SPF systems that do FOLLOW the
specification 100% and if you have a HARD PASS/FAIL "-ALL" result, it will
honor your wishes.   Atleast, HOTMAIL.COM and GMAIl.COM should of rejected
your intentionally created bad transactions.

Try it against our server, at santronics.com or winserver.com

or use SPF testing web page:
