ISPConfig 220.127.116.11 - Mail() does not route to remote MX when to domain on local server
I hate to ask a question for my first post, but I have a route added to transport to google's IP. This is added under Advanced Email Routing. The domain uses google apps.
When I try to send an email using PHP's mail() function to any other email address, it works fine. When sending to an email address of a site on the local server, it tries to route it to localhost:
Mar 28 15:01:31 vds1 postfix/smtpd: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 550 5.1.1 <firstname.lastname@example.org>: Recipient address rejected: User unknown in relay recipient table; from=<email@example.com> to=<firstname.lastname@example.org> proto=ESMTP helo=<xxxxxxxxxxx.com>
Mar 28 15:01:31 vds1 sendmail: r2SC1UVX000652: email@example.com, firstname.lastname@example.org (48/48), delay=00:00:01, xdelay=00:00:00, mailer=relay, pri=30079, relay=[127.0.0.1] [127.0.0.1], dsn=5.1.1, stat=User unknown
The domain xxxxxxxxxxx.com is added as a site, but not a mail domain. Do I have this configured wrong, or is something else wrong? This is causing a form to not properly deliver emails.
