Postfix 550 - User unknown in virtual mailbox table / google apps
People, right now I have a site (oscommerce) that uses a form to send a mail from the page...
As I understand, the error that I am getting is that "email@example.com doesn't exist". That is true, that mailbox doesn't exist because mx records for this domains are pointing to google apps.
Jun 16 16:02:29 mx1 postfix/smtpd: NOQUEUE: reject: RCPT from site1.tecatest.com.ar[126.96.36.199]: 550 5.1.1 <firstname.lastname@example.org>: Recipient address rejected: User unknown in virtual mailbox table; from=<email@example.com> to=<firstname.lastname@example.org> proto=ESMTP helo=<site1.tecatest.com.ar>
So, I have a multiserver enviroment. site1 is web server, it only wait for emails from localhost, and relay these mails to mail server. Mail server rejects them with error 550...
How can I solve this? I need that emails go first to dns, and then define where to be relayed (to my mailserver or to another server, eg: google).
Do I have to change something in main.cf of my mailserver? maybe "mydestination value"?
My mailserver is named: mx1.tecatest.com.ar
mydestination = mx1.tecatest.com.ar, localhost, localhost.localdomain
