I have installed virtualmin some time ago and configured some domains on it, including mail delivery and all.
Now for one domains the user want to use a different server for his e-mail. It is google apps. All works fine for the normal e-mail. I conffigured the DNS records at the domainregistrar. It’s all delivered on the new Google apps server. Only the mail that is created/send of the website on the virtualmin server it’s still delivered on the virtualmin server.
I thought it had something to do with internal DNS of virtualmin, but don’t know where to start. I already tried to disable mail delivery for that domain, but that doesn’t fix it.
Anyway how to correct this?
