DKIM for Alias Maildomain is not actually used?

    Hello,

    I have set up an Alias Maildomain for an existing Maildomain. I have let ISPConfig generate a DKIM key for the Alias domain, too. Now I can use [email protected] as well as [email protected] as the sender of e-mail, but when I use [email protected], no DKIM entries are included in the e-mail message headers.

    Have I hit upon a bug that needs to be fixed before this will work, or did I miss something?

    (I'm using ISPConfig 3.1dev, stable branch, April 2019, in the "Perfect Server" setup for Ubuntu 16.04, Apache, PHP, MySQL, PureFTPD, BIND, Postfix, Dovecot)

    Cheers,
    Etc

    Hmmm..... Am I the only one having this problem, or am I the only one trying to use DKIM with an alias mail domain? ;-)

    Please check your dkim config file and double-check that you really activated the amavis key for the aliasdomain and not just generated it, there is an active checkbox.

    The Dkim config file on Debian and Ubuntu is:

    /etc/amavis/conf.d/60-dkim

    It should contain lines like this for the alias and the main domain:

    dkim_key('testalias.int', 'default', '/var/lib/amavis/dkim/testalias.int.private');
    dkim_key('test.int', 'default', '/var/lib/amavis/dkim/test.int.private');

    It turned out everything was properly entered in ISPConfig, every necessary checkbox checked, but nonetheless the alias domain's entry was missing in /etc/amavis/conf.d/60-dkim. Unchecking and re-checking the mark for the alias domain's DKIM activation did the trick...

    Thanks,
