    Care to elaborate a little? I'm having the same problem but I have A and MX records on both my server and my domain registrar and as of upgrading to 10.8 Server my mail server won't send or receive email.


    The 'Forwarding Server' in my DNS panel is set to my router. I have one host name set to my server's IP and the create MX record checkbox is checked. When I show all, it expands the one entry into three lines that all say the same host name but with different words after them... 'machine', 'mail exchanger', and 'name server'.


    At my registrar, I created an A record for and pointed it to the static IP of my Mac mini... I created an MX record this name as well.


    What am I doing wrong?

    If you post your real domain, we can lookup your DNS.

    But yout post mentions that you upgraded to 10.8, so your problem is likely the server config and not DNS.

    (if your public DNS worked with an older server, it should work with the new).


    We need to see snippets from your mail logs.


    Post that info and we'll move forward.

    I received this message from Apple...


    The problem you are encountering is a known issue and will be resolved in a future Server update. In the meantime you can resolve by going into Terminal and entering the following:


              sudo serveradmin settings mail:postfix:required_hits = 6

    Problem solved immediately!
