SPF record issue

Dear All

Some people told me that my SPF record is not correct.
"include include:concordia.mo" is having problem.

I am not fully understand the syntax.

How should I modify it?

The Public IP of the mail server is  202.175.126.170
Is the following ok to use?
please provide some suggest.

concordia.mo      IN      TXT      v=spf1 mx ip4:202.175.126.170 ?all      86400s

first of all, what is your rules(goal).. allowing all servers? allowing only mx? after that you can setup the SPF. also you can use mxtoolbox as syntax checker
