centos 6.6 - user dkim-milter does not exist
I have a problem using dkim on my new fresh centos 6.6 installation. I use virtualmin/webmin and when i am going to “Email Messages” -> “DomainKeyIdentifiedMail” i try for the first time to save a dkim record, by changing the name to 2015 and checking “Signing of outgoing mail enabled?” to YES.
As I click the save button, I see the message I have below:
The user dkim-milter does not exist as I double-checked on my system by running “cat /etc/passwd”.
I reinstalled dkim-milter and I receive the same error. I have another server with same configuration and its worked there from the start. I am not able to reinstall the system.
dkim version is the "dkim-milter-2.8.3-8.el6.x86_64
I also tried to use this tutorial to install it again:
but when I am at the end of step 3 and try to start dkim-milter I get again in the console:
Starting DomainKeys Identified Mail Milter (dkim-filter): runuser: user dkim-milter does not exist
I also find out that I was unable to create a user “test123” via ssh terminal, as I get:
adduser: cannot lock /etc/passwd; try again later.
-rw-r–r– 1 root root 2871 Mar 6 06:39 /etc/passwd
Why this is happening?
How can I fix this problem? I cant seem to find a similar problem on the net.
