? ? Let me give a brief explanation of how it works.You publish SPF
records for your domain. So, in your DNS, you add entries like
mydomain ? ? ? ?IN ? ? ?TXT ? ? "v=spf1 +mx -all"
Correct me if I am wrong but what has MX records got to do with SPF records?
I was just explaining my example :). When you define an SPF
record with a +mx record, all A records of all MX records are actually
checked. The link below explains it.

MX is for receiving mail, SPF is for sending...
Or am I wrong?
May be I didn't put it in a clear way.
SPF is for the receiver of your mail to see if the mail actually came
from your network.
MX is need when some one sends an email to you. His SMTP server looks
up for MX records in your DNS and sends it to that server.(Of course,
it is more complex that a single like :) ). thanks
