Question : SPF policy not working
Hi,
I installed SPF as per the following instructions
http://www.howtoforge.com/
postfix_sp
f
Once implemented, I signed up to hoaxmail to spoof an address and see if it works. I basically had the envelope header say I was
[email protected]
and send to my email account via my smtp gw (which has spf installed).
ok, ive installed SPF on my Mail Gateway (its a centos box)
I signed up to hoaxmail.com to test the SPF, here are the results...

What am I missing?
Answer : SPF policy not working
There is also a guess mechanism that you can turn on. Usually set to
a/24 mx/24 ~all
What this does is allow any computer in the same c class network as the senders servers to get an spf pass.
