So I'm trying to setup my email on a Basic DigitalOcean droplet (Centos 7) to be used with Postfix. All the DNS records are in place and working fine but every email I send through postfix is being flagged as SPAM by Google. If I send the message through an email client, it works fine, even on Gmail. 

I've searched the Forum and every topic response basically points back to the SPF and DKIM DNS records. Mine are in place and verified by Zoho (I have the green check mark on my dashboard under Domains). The domain is devdan.net.

Can somebody point me in the right direction? 

Thanks,

Daniel M.
