I have a domain hosted at Jodo - the server IP is 220.127.116.11. The domain is using Google Apps, and has everything configured within the DNS section of the Jodo control panel. The domain is registered through GoDaddy, with Custom NameServers pointing to Jodo NS Recently I've been having issues SENDING emails - I checked and the domain name and it shows the IP address for the hosting has been blacklisted! If I check mail.mydomain.com it's fine - the blacklists only come up when I check mydomain.com Do I have something mis-configured? It looks like the major email providers (like Comcast and ATT) are fefusing delivery based on the server IP - do I need to create a support ticket?
