That&#x27;s not right, I host some email servers for small companies and private people who all have problems with Google accounts although supporting DKIM, SPF and a TLS connection. They block them as bulk mail and in their FAQ the option hosting your own server isn&#x27;t even listed. Of course contacting them is impossible, so the only way left is creating a ton of fake accounts on gmail and add the addresses to their contacts or ask friends with gmail accounts to add them and mark them as no spam. Google definitely IS the email bully and there&#x27;s not much you can do about it.
