When sending email to users on my domain, I get the following returned mail from postfix: Code: This is the Postfix program at host www. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to <postmaster> If you do so, please include this problem report. You can delete your own text from the attached returned message. The Postfix program <[email protected]> (expanded from <[email protected]>): Host or domain name not found. Name service error for name=www.www type=A: Host not found I saw another post where the domain wasn't in the local-host-names file, but here is my local-host-names file: Code: ################################### # # ISPConfig local-host-names Configuration File # Version 1.0 # ################################### localhost www localhost.www www.liquidlightning.com liquidlightning.com mail.liquidlightning.com SPConfig local-host-names Configuration File #### MAKE MANUAL ENTRIES BELOW THIS LINE! #### Can anyone help me find the problem why my email server thinks the email address [email protected] is [email protected] ? I'm sure it's a hastname problem somewhere as I seem to be struggling with this whole hostname thing (and I thought I finally understood it.) Thanks
You may want to manually check your MX records / A records ( I had a few MX problems and had to resolve them by editing the dns records by hand). I checked for your domain's mx records and this is what I got from dnsstuff.com check etc/bind/pri.liquidlightning.com to see if it is correct
There is no /etc/bind/ I guess this could be a problem? There is no /etc/bind so I guess there wouldn't be a pri.liquidlightning.com either. I thought Bind was running, but now I'm not sure.
A Record question Should my liquidlightning.com A record be my external IP address, or my internal IP address? I'm running it behind a router with all the necessary ports forwarded.... I thought I had everything configured correctly because it's all working right... I can create websites/email users/ftp/etc, and all the logins work, ftp works, sending mail works... it's just receiving email that doesn't work. Right now my mail A records looks like this: Code: A Record ----------------------------------- IP-Adresse Hostname 158.91.201.193 mail 192.168.1.125 www MX ----------------------------------- Mailserver Hostname liquidlightning.com mail Should my mail A record be an internal IP?
My understanding is this: whenever a computer requests a website they goto the nameserver of that site to get the A record for the host www for your site. Then your computer attempts a connection by going to that ip address that was in the A record. Thus you would want your nameserver to tell any visitors that your www.liquidlightning.com is at your external ip (so they can actually see it!) Same thing goes for the mail, MX records. The only time you would want internal records on a nameserver is if that nameserver is acting solely as an internal nameserver for you lan, because your lan can see those local ip's.
Fedora Core 4 Code: Which distribution do you use? I'm using Fedora Core 4. Also Falko (or anyone else) as per the first post, is there another reason why I get this in the returned email I send to my domain from an outside email address? Code: <[email protected]> (expanded from <[email protected]>): Host or domain name not found. Name service error for name=www.www type=A: Host not found Thanks
On Fedora 4 the zone files are in /var/named/chroot/var/named. There's no directory /etc/bind. You have to create an MX record for liquidlightning.com. Currently there's no MX record, as this shows: Code: server1:~# dig MX liquidlightning.com ; <<>> DiG 9.2.1 <<>> MX liquidlightning.com ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 42704 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;liquidlightning.com.

Ok, I think I'm starting to understand the problem, but, any suggestions on how to resolve this? I checked in the ../named/ folder as you said my domain name would be in, and it was, with lots of info in the file... including an MX line: Code: mail MX 10 liquidlightning.com. liquidlightning.com. A 158.91.201.193 mail A 158.91.201.193 www A 192.168.1.125 ns A 192.168.1.125 ns1 A 192.168.1.125 So, as you described in your DiG, Code: ;; AUTHORITY SECTION: liquidlightning.com. 7200 IN SOA ns5.zoneedit.com. soacontact.zoneedit.com. 1037464252 14400 7200 950400 7200 ;; Query time: 286 msec ;; SERVER: 81.169.163.104#53(81.169.163.104) ;; WHEN: Sun Oct 23 12:58:26 2005 ;; MSG SIZE rcvd: 97 Before I setup this server, I had to use Zoneedit for my DNS, hence the ns5.zoneedit.com, but I thought ISPConfig was a DNS server as well. I'm using GoDaddy as my registrar, and when I tried to put in ns.liquidlightning.com and ns1.liquidlightning.com as the DNS servers, it said: Unavailable error in field Host name1 Unavailable error in field Host name2 I'm assuming that if I can get GoDaddy to accept my DNS, my server will be able to resolve all the A/MX/etc records and everything will be fine... is this not right? I have port 53 forwarding to the server, is this the correct port? Also, I noticed there are 3 other ports open: Port 5335 (tcp) is open (unknown)! Port 32769 (tcp) is open (unknown)! Port 55512 (tcp) is open (unknown)! Are these used by ISPConfig? Do I need to have them forwarded in my router also? Or can they be left alone? *Edit* I just noticed... the IP address is wrong in that Bind file. That's the IP of where the server *will* be... it's on a temporary IP right now. Is that why Godaddy isn't resolveing ns.liquidlightning.com? If I change that to the temp IP, would that fix it? *Edit*
Yes, that's right. You have to make your nameservers authoritative for your domains. Yes, but it's port 53 TCP and UDP! No, these ports aren't used by ISPConfig. I don't know what's running on these ports, so if you don't know this either, you should better close them... Hm, I think you should contact the GoDaddy support about this... - or just try.
