Hi, as already mentioned in another post, I try to setup my server using ansible scripts. Current state of the development is here: github.com/ruppel/myserver (I took perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/ ) My system is debian10, apache, postfix, dovecot, php-fpm, PureFtpd, ISPConfig 3.2.1 Check out the htf_report.txt attached. My problem is, that the documented links for using mailman are not working on my site. I always get 404 errors. These are: server1.example.com/cgi-bin/mailman/admin/ server1.example.com/cgi-bin/mailman/listinfo/ and server1.example.com/pipermail No one of them work and I checked a lot of logfiles... Cheers and thanks in advance for your help, Ruppel
