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:

DNS: https://temporario.clubenaval.org.br/zohomail/DNSok.jpg

Domain: https://temporario.clubenaval.org.br/zohomail/DominioOK.jpg

MX: https://temporario.clubenaval.org.br/zohomail/MxOk.jpg

Logs Zimbra: https://temporario.clubenaval.org.br/zohomail/LogsZimbra.jpg

I tried to send several emails from the address henrique@aprendendolinux.com (zimbra) to henrique@linuxadmin.com.br (zoho) and nothing comes.

I look at the Zimbra LOGs and the message was sent correctly

Does anyone know what can be happening?
