Hello, How to create domain forwarders for non existing emails on my virtual server? I have postfix installed and configured. On top of my configuration file in /etc/postfix/main.cf I have: email@domain.com existing@gmail.com email1@domain.com existing@gmail.com email2@domain.com existing@gmail.com In my domain zone I have Gmail MX records automatically set, but I don't know what I miss or doing wrong. Any help?
I set up an SMTP server on a CentOS 7 droplet. Emails are successfully being sent to Gmail accounts, but they are failing to send to my G Suite email accounts. Successful email: Jan 1 13:35:48 Production postfix/smtp[2869]: E5B653FDBA: to=<personal_email_address@gmail.com>, relay=gmail-smtp-in.l.google.com[209.85.144.27]:25, delay=877, delays=876/0.02/0.31/0.25, dsn=2.0.0, status=sent (250 2.0.0 OK 1483295748 k58si25466087qta.76 - gsmtp) Failed email: Jan 1 13:35:48 Production postfix/lmtp[2871]: E5B653FDBA: to=<root@example.com>, orig_to=<support@example.com>, relay=none, delay=876, delays=876/0.02/0.02/0, dsn=4.4.1, status=deferred (connect to example.com[/var/lib/imap/socket/lmtp]: No such file or directory) Jan 1 13:35:48 Production postfix/smtp[2869]: connect to gmail-smtp-in.l.google.com[2607:f8b0:400d:c0e::1b]:25: Network is unreachable I replaced my domain name with example.com above. I was able to fix the "Network is unreachable" by opening /etc/postfix/main.cf and setting the following: inet_protocols = ipv4 However, the other error is still present, and emails are still failing to send to my domain accounts: Jan 1 17:22:38 Production postfix/lmtp[4066]: 9EC3E3FE3C: to=<root@example.com>, orig_to=<support@example.com>, relay=none, delay=1104, delays=1104/0.03/0.01/0, dsn=4.4.1, status=deferred (connect to example.com[/var/lib/imap/socket/lmtp]: No such file or directory) Why is Postfix able to send emails to all domains except the one that it's running from? How can this be fixed?
