Hello, I am trying to setup an e-mail with ISPConfig. All seemed to be working until I say my deferred e-mail for Postfix. I am getting the below error message in my mail.log. Mucho thanks for any help.

Name service error for name=juno.com type=MX: Host not found, try again) I used the HOWTO for the perfect server setup on Ubuntu 6.10. Below are some config files for Ubuntu. I own the domain www.builderbulletins.com. I made the hostname for my Ubuntu box www.builderbulletins.com. I made my MX record www.builderbulletins.com.

I would try this: Change myorigin= builderbulletins.com within myorigin = /etc/mailname The file /etc/mailname should contain your fqdn like host.builderbulletins.com If the output of hostname -f is server1.builderbulletins.com put server1 as the host. Change smtpd_sasl_local_domain = within smtpd_sasl_local_domain = $myhostname What is your output of hostname -f anyway?
Thanks Thanks for the reply. My host is www. I made the suggested changes and rebooted and it is still giving the same error message. hostname -f is www.builderbulletins.com. Is this wrong?
Name That is what I named it. Below is my /etc/hosts. 127.0.0.1 localhost.localdomain localhost 192.168.2.1 www.builderbulletins.com www
In principle you did it right, but i would prefer a different name for your host then www, for instance server1. Is the output of the command: hostname the same as for the command hostname-f ? Do you see any errors whitin your mail log files?
Hostname Hostname and hostname -f produce the same output. I can change it to server1 but would that mean my MX records change also? The error I have been getting on every e-mail sent has been....

This looks as if your system cannot resolve domains. What is within /etc/resolv.conf? Are there any DNS servers in it?
Nameservers My resolv.conf is (Which are my ISP's name servers) nameserver 216.199.XXX nameserver 216.199.XXX.XXX
Solved Thank you for all of the great help. I ended up naming the box server1.builderbulletin.com and changed it all in the corresponding Postfix config files. I also put my nameserver to 127.0.0.1 in Resolv.conf and the resolved all of the DNS. I would assume because of bind. Thanks again, I am glad there are people here to help.
