I configured postfix on my server, but when I send an email to firstname.lastname@example.org I get 2 emails, the email I sent and another email with delivery error. I tried many solutions without success. The error email that I receive is the following:
Delivery to the following recipient failed permanently:
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain ogreshop.com.br by ogreshop.com.br. [18.104.22.168].
The error that the other server returned was:
