    I followed the instructions and everything installed fine. My domain is nunyad.biz. I can send emails fine but receiving them is an issue. My server is behind a firewall. Is there any way I can test to see if the firewall is configured correctly? HTTP, HTTPS,POP3 and STMP are all enabled and forwarded but emails get returned.

    Here is some server info:

    dig mx mail.nunyad.biz
    Code:
    ; <<>> DiG 9.3.2 <<>> mx mail.nunyad.biz
    ;; global options:  printcmd
    ;; Got answer:

    I've tried sending emails to my server both ways and neither works, but I want to go with the [email protected] format.

    I'm located behind a firewall - NAT device and I found the problem to be a DNS problem. There is some mention about it in the beginning of the" How To", but nothing in detail about MX records and such. I found some instructions on DNS in "The Perfect Ubuntu Server Setup ". I also looked in the Zimbra forums and found a thread on split-dns. Between the two, I was able to get it going. Thanks for the help...

    Please share how you got this working as I am having many problems with this part of the DNS, and would appreciate any assistance, other than that I'm good to go. I too am behind a NAT firewall but I have all ports forwarded to that IP, suggestions?

    How does your MX record look?

    I found another tutorial that shows how to set up a split-dns. I still don't understand the whole DNS thing yet. The other tutorial has emails coming and going as [email protected]. I really want emails as [email protected]. I followed your "How To Install Zimbra Collaboration Suite (ZCS) On Ubuntu" and right before installing zimbra did this:

    1) apt-get install bind9

    2) edit /etc/hosts
    Code:
    127.0.0.1       localhost.localdomain localhost
    xxx.xxx.xxx.xxx  mail.MYDOMAIN.com mail
    ***configure bind for split DNS.***

    3)edit /etc/bind/named.conf.options
    Code:
           // forwarders {
          //      0.0.0.0;
          // };
    Uncomment and change to reflect your own upstream DNS servers.


    Code:
          forwarders { 
          xxx.xxx.xxx.xxx; xxx.xxx.xxx.xxx; 
          };
    4) Append to /etc/bind/named.conf.local

    Code:
          	// We are the master server for mail.MYDOMAIN.com
          	zone "mail.MYDOMAIN.com" {
          		type master;
          		file "db.mail.MYDOMAIN.com";
          };
    5) Create the zone file: /var/cache/bind/db.mail.MYDOMAIN.com

    Code:
          ;
          ;       Addresses and other host information.
          ;
          @       IN      SOA     mail.MYDOMAIN.com. hostmaster.mail.MYDOMAIN.com. (
                                         10118      ; Serial
                                         43200      ; Refresh
                                         3600       ; Retry
                                         3600000    ; Expire
                                         2592000 )  ; Minimum
          ;       Define the nameservers and the mail servers
                         IN      NS      xxx.xxx.xxx.xxx
                         IN      A       xxx.xxx.xxx.xxx
                         IN      MX      10 mail.MYDOMAIN.com.
    6) Modify /etc/resolv.conf -- Change upstream name servers to your own IP:
    Code:
    nameserver xxx.xxx.xxx.xxx
    7) /etc/init.d/bind9 reload

    8) To test it, nslookup mail.MYDOMAIN.com should point to xxx.xxx.xxx.xxx


    What would have to change or be added to get [email protected] to work?
