I have just started to use the zoho mail services. I have registered the domain. My account is verified and mx records are also ok. But for some reason, the spf records are not validating .

i used the this spf record first v=spf1 include:zoho.com ~all and the i saw on some post they said to use 

v=spf1 mx include:zoho.com ~all. 

But both are not working.. Please advicee

My domain - conceptqatar.qa
