Dear all, I need to know if the SPF protocol used in DNS's and mail

a new protocol without future in Internet.
You can find out if a given domain is using SPF by querying for the TXT
record:
$ dig +short halfcoded.net txt
"v=spf1 a -all"
I've tried to experiment with it for my domains but I am not using it
live yet. The problem I had was trying to "see it working": a lack of
client software for checking a given mail.
We use it at work but we only SOFTFAIL.
