I am using outlook to send and received emails through zoho, and today my outlook is not able to send out emails, i went to check the admin account and found out that there was SPF record problem, I did as instructed adding the txt file onto my blue host DNS Zone Editor but i am still having the same problem sending out emails.

I registered my domain at namecheap.com and direct it to my host: bluehost.com, then on blue host i added the MX and also the txt. I have not experience this problem before on sending issues on my outlook. please help, attached are some screenshots.
