OS: GNU/Linux Debian 9.2 64-bit

I disabled IPv6 on one of my servers.

And now I'm getting this in mail:

exim paniclog
IPv6 socket creation failed: Address family not supported by protocol

How do I get rid of it?


First of, man needs to disable IPv6 in exim4.

In the following file:


Make sure this line is there, if not, add it, or change it:


But I tried only this solution and the mail is still coming, so digging further...

In the same file, make sure this line is set to true:


Now edit this file:


Let's suppose, this line defines your server name:   server-name

Change it as follows:   server-name.localhost server-name

Now, verify, that this command:

hostname --fqdn



If so, you can update your Exim4 configuration:


And restart the Exim4 service:

service exim4 restart
