We have a server set up with several domains. We want to be able to forward emails to external domains (like gmail) from two of our domains.
The two domains in question are the ones shown in the picture. For our name.lat domain we can properly forward emails to gmail, but when we try to do the same form the .space domain, we get an automatic response form the google servers with the following text: “Our system has detected that this message is 550-5.7.1 likely unsolicited mail. To reduce the amount of spam sent to Gmail, 550-5.7.1 this message has been blocked.”
Both domains have the correct DNS configuration as per the instructions in the mailcow configuration page.
Is there any external configuration or something we could be missing in order to make the forwarding work?
