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 someone@aliasdomain as well as someone@maildomain as the sender of e-mail, but when I use someone@aliasdomain, 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');
And Florian has published a guide to debug Dkim issues: https://blog.schaal-24.de/dkim/debug-2/?lang=en
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, Etc
