Hello, I hope that you will understand my question, as my english is not as good as it should be. Only the web service is used on the server, the mail server is on another server. If i try to send email using mail() (php function) to firstname.lastname@example.org, the mail are not sent. I think that the server try to delivred them locally. I didn't register the domain in the email panel. in the /var/log/maillog, postfix seems to try to send it to the good server (the ip is not my server) but the mails are not sent... How can i fix it ? Thanks.
