I don't get it. Your friends wouldn't be paying to connect to your Ipv4.

I think the idea is that he has friends with SMTP outbound that is only capable of ipv6. Zoho doesn't listen on any ipv6 addresses, and doesn't have any MX records that map to AAAA/ipv6, so mail from them doesn't get to Zoho.

Though I suspect Zoho is not the only medium sized email provider that doesn't support ipv6.
