HI, To be sure i followed this tutorials to install ISPConfig 3.1.11: Debian 9 (Stretch) Minimal Server + The Perfect Server - Debian 9 (Stretch). Everting is working fine now except the Mailman, every Mailman link i click i get a 404 error page. On my old server Debian 7 (Wheezy) Mailman is working but on my new server Debian 9 (Stretch) it isn't working. I never played around with Mailman so i'm not sure what i should do to fix this problem.
The links generated by mailman in it's mails are wwrong. Try to replace the domain in that links with the server hostname.
Okay now it gets weird. After i updated and restarted my Server i can now access Mailman, but now i get the 404 page error at the ISPConfig Login page (https://server1.domain.tld).
I did use port 8080. But now after a seconed Server restart ISPConfig Loging page works again. But i now found out why MailMan is not working, ass soon as i enable "SuEXEC" on a Website MailMan gives a 500 page error. Is there any fix for this?
See my post #2, you have to use the hostname of the server instead of the domain that is used in the mailman links. Copy one of these links, replace the domain inside the URL with the hostname and try again. There is also a workaround for this in the ISPConfg bug tracker.
I did use the URL "http://server1.domain.tld/cgi-bin/mailman/admin/" but it looks like there is a conflict between MailMain 2.1 and suExec on Debian 9 Stretch. The tutorial should have installed Mailman 3.1 instead of Mailman 2.1. Now i don't know how to fix this.
