I am so sick and tired of dealing with this. I have been trying to simply send emails on Gmail with my Zoho email. I have a purchased account and have already completely linked the zoho email for sending and receiving on gmail. whenever I send an email however, it bounces. I cannot find a straight forward answer on how to fix this. 

I have the DNS records to what they are supposed to say according to other posts, I use Gandi for my domain. My admin console for zoho says my MX are all good for pointing to Zoho. i am at a complete loss.
