Gentlemen,
I ask your help for the following question: I configured my ZohoMail for the domain linuxadmin.com.br
Everything seemed to work fine, I send and receive emails from common providers (gmail/yahoo/hotmail/etc).
However, if my sender is a private server (Zimbra / Postfix / Exim / etc), I simply do not receive the email. And I do not even get an error message.
If I send an email, it receives correctly, however I do not.
I have my domain verified correctly, DKIM ok, SPF ok, DMARC ok, MX ok.
Here are the prints of the checks:
I look at the Zimbra LOGs and the message was sent correctly
Does anyone know what can be happening?
