mail daemon

[alan_131]

My notifications are not working properly. One of my server is the dns server. On the dns server I've got a error logs like this
"Unable to qualify my own domain name"
and " be sure to set the domain name in Dj macro in sendmail.cf".How can i resolve my problem?

regards

Hi Allan,

Make sure your 'hostname' is associated with a domain.

nslookup $(hostname)

if it doesn't return 'hostname.yourdomain.com', then add it to your /etc/hosts like

xx.xx.xx.xx hostname hostname.yourdomain.com

Ensure that yourdomain.com is specified in your /etc/resolv.conf file.

You should have FQDN in /etc/hosts file.
