Hi. Having issues with this. Emails comes in randomly. But most of the part, emails from Yahoo, Gmail can't go through and popping up with this error 553 Relaying is not supported. I've checked the domain MX records and it's there. On the CPanel WHM side though on the Advance DNS Zone editor, you can only add CNAME, A, and TXT records. Just wondering if that's an issue there. Also, I've check both IP and domain name for blacklistings, and there are none.

Hello,

Could you let us know the full bounce error that you receive when attempting to send email? Also, to clarify, is this issue when sending email or receiving email? Do you have root access to this server?

Thank you.
