Testing?

I am confused...
Has "v=spf1" replaced "<ep><out>"?
Or are these 2 competing methods?

Also, I would like to test my setup.  Is there an email address that I can
send to to test my spf1 record?  I would hope this email address would auto
reply with a report of some sort.  At least a pass/fail message.

Also, I am for opt-in.  And the opt-in can't contain any spam!

Thanks,
Guy
