Ok but email send perfectly but not received I setup also mail.baby relayI think google cloud blocks SMTP trafic, thus making sending e-mail impossible, unless you use a smtp-relay.
I they also block outgoing trafic, so recieving might not work either.
Do you have an MX record for your domain?Today I set up Google cloud vm
But when I send email anyone email received but he reply to me not received email
Please helpnus
