I cannot receiving any emails

Hello,
I facing problem in receiving emails, sending is ok, 
I have set everything MX records like this tutorial in this page , and i also setting SPF this video tutorial , but I still got this notification "Zoho Mail SPF entries in your domains DNS are not configured to match with undefined. Configure SPF to for better email deliverability." even though I test every thing here's the result of MX lookup
