mailx: getipnodebyaddr (IPv6:::1) failed: 1

[Tariq Hasan_1]

Hi

I am using a current and working sendmail.cf file, but when sending mail, I am getting the entry in mail log:

Jan 3 11:08:37 ******** sendmail[14462]: unable to qualify my own domain name (********) -- using short name
Jan 3 11:08:37 ******** sendmail[14462]: be sure to set domain name in Dj macro in sendmail.cf

138, dsn=4.4.3, stat=queued

where ******** is the hostname

Can you help?

You seem you be have found:

Install a later version of sendmail or use the IPv4 addressing system.

Shalom Tariq,

DNS name lookup failed.

/etc/resolv.conf

Use dig or nslookup to make sure you are getting good answers.

By default, sendmail will try and lookup the hostname of the recipient and directly deliver the mail.

If this is not permitted by your firewall, you may need to use an smtp relay server on your local network.

The simple way of doing that is the DS directive in sendmail.conf
DShostnameofrelayserver

You will need to check with network administration to see what the policy is.

Can you resolve your own hostname both ways ? (name to IP and other way around)

Also, do you have an nsswitch.conf file ? If not, make one and make sure this line is in:

hosts: files [NOTFOUND=continue] dns

Then, put the mail server in your /etc/hosts file.

Still the same problem then ?

Thanks

Putting in the nsswitch and resolv .conf files did the trick.
