I tried to set up with Zoho mail yesterday and went through the setting up process. I added MX records correctly etc and have left it over night to see if it would just take time but it is still not working. 

I can send emails out from the Zoho account but I can't send them back to myself from my hotmail.

Additionally, when I sent an email to myself from the Zoho to my hotmail, it directed straight to Spam even though it was a text only email. Is there a way to reduce this?
