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: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 13560 ;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 2, ADDITIONAL: 3 ;; QUESTION SECTION: ;mail.nunyad.biz.

You must check if there's an MX record for nunyad.biz, not for mail.nunyad.biz (or do your emails have the form [email protected]?).
I've tried sending emails to my server both ways and neither works, but I want to go with the [email protected] format. dig mx nunyad.biz Code: ; <<>> DiG 9.3.2 <<>> mx nunyad.biz ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 46318 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 2, ADDITIONAL: 3 ;; QUESTION SECTION: ;nunyad.biz.

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? -Dijital
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?
