SPF in DNS's and mail servers
Dear all, I need to know if the SPF protocol used in DNS's and mail
servers to avoid spam is used by a lot af administrators or it's just
a new protocol without future in Internet.
I'll go to edit my zone files in the DNS's with the SPF fields in order
to let other mail servers check them to know if sender domains are valid
or invalid (spammers).
Thanks a lot,
