Re: Error FQDN, Please configure Fully Qualified Domain Name

It's mentioned in iRedMail installation guide:
http://www.iredmail.org/install_iredmai … t_hostname

WARNING: iRedMail is designed to be deployed on a FRESH server system, which means your server does NOT have mail related components installed, e.g. MySQL, OpenLDAP, Postfix, Dovecot, Amavisd, etc. Otherwise it may override your existing files/configurations althought it will backup files before modifing, and it may be not working as expected.

Re: Error FQDN, Please configure Fully Qualified Domain Name

Hi, I have read you post on configuring the FQDN, but I am a newbie and would like some help. Here is my /etc/hosts content:

127.0.0.1       localhost
127.0.1.1       ubuntuserver
127.0.1.1       ubuntuserver mail localhost localhost.localdomain


# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters


I have an email host name devitt.4pu.com or mail.devitt.4pu.com

How should my /etc/hosts file look like. I am running Ubuntu 12.10. I do not have mysql running.
Clinton

It should return only one fqdn hostname, why it's "mail.myserver.si   localhost"?
