here is the situation: we had a mail server configured within a VPS (using Postfix/Dovecot) with the mail for 1 domain being managed.
We just moved the mail for that domain to Google Apps.
The MX records are working fine, and we can receive the email that the rest of the world send us. But the email from our VPS (mostly, notification for a couple of webapps and system tools like Logwatch) are being delivered locally.
The VPS sends email properly to any other domain, but enroute the mail for our own domain internally, without sending it to Google Apps. We want that mail to be route through the Internet to the Google Apps mailboxes.
How do I get the VPS to send the domain for the domain to the new inbox in Google Apps? Where do I need to start tuning the config for Postfix/Dovecot? I'm very new to mail servers and I don't know exactly which of these two applications is responsible for the mail being delivered/routed locally.
I've been diving into ServerFault and found a question about the pros and cons of moving (not exactly what I'm needing right now), a few less-related though still interesting questions, and a very similar question that has an answer but does not explain what I would like to do.
So, anyone has an idea on how to reconfig the system on the VPS to get it to deliver the mail?
I'm not a sysadmin and I'm a bit lost on how to proceed. This is my first question in this SE site :)
Thank you all.
