[Solved] DKIM rmilter error

Hi. I just did the upgrade from 2.4 to 2.5. It seems that I have the same problem.

First, I update/upgrade all using the web administration panel.

Secondly, cron send me a first mail with : https://paste.yunohost.org/oyavilebav.vhdl. As you see, there was an error in rmilter too…
One our after, new mail (as the first cron failed) : https://paste.yunohost.org/afobutufib.vhdl. Same problem.

So, reading this thread I did :

 yunohost service regen-conf rmilter --force

Then manually run the upgrade script :

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin apt-get install yunohost moulinette yunohost-admin ssowat -y && rm -f /etc/cron.d/yunohost-upgrade

I entered “Y” when it asked me for rmilter (see log : https://paste.yunohost.org/dehozarara.vhdl).

Now, it seems to be ok for me as

systemctl status rmilter.service

shows Active: active (running)

However, I do have something wrong :

systemctl status rmilter.socket

gives me : Loaded: not-dound (Reason: No such file or directory) https://paste.yunohost.org/fuquvumupa.pas

EDIT :
Based on this post, it seems to have a configuration problem in /etc/rmilter.conf.common:

dkim {
    # Sample for dkim specific keys
    # domain {
    #   key = /etc/dkim/dkim_example.key;
    #   domain = "example.com";
    #       selector = "dkim";
    # };
    # domain {
    #   key = /etc/dkim/dkim_test.key;
    #   domain = "test.com";
    #       selector = "dkim";
    # };
    # Universal selector, keys will be checked for pattern /etc/dkim/<domain>.<selector>.key
domain {
            key = /etc/dkim;
            domain = "*";
            selector = "dkim";
    };
header_canon = relaxed;
body_canon = relaxed;
sign_alg = sha256;

};
The selector “dkim” is not the good one as in /etc/dkim/ the name is domain.ltd.mail.key and not domain.tld.dkim.key.
