Unable to get emails MX and SPF errors

HI 

My emails aren't coming through when i login to the admin area it tells me the MX and SPF needs action when I go to my domain all the MX and SPF are correct.   I can't understand why as the information is correct as hasn't changed changed in the last 4 days.  Any idea?

Thanks
