How to setup backup mx entry for domain

  • Hello everybody,


    I played around a little bit with the latest Git master on an Ubuntu 12.04 LTS machine. I tried to setup a secondary mx entry for one domain running on the machine.
    If I remember correctly (did not find the thread anymore) I read somewhere in the forum that if I enable external mail server feature for this domain with both servers as e.g. mx10 and mx20, and afterwards also add the corresponding IP A entries to the custom dns feature, I would be able to receive mails with i-MSCP for existing mailboxes.
    But when I try to send an email to the created mailbox I always get "mail for XXXX loops back to myself" (domain name replaced by XXXXXX). Sending out mail from the mailbox works.
    When the mail is send to an address (hosted on the same server for the same domain) which is configured to just be a forwarded the mail is delivered.


    Anybody an idea what went wrong?
