First thank you for your help.
I have followed the instructions in tutorial: http://www.howtoforge.com/perfect-se...ispconfig-3-p4
. I have re-installed the server 4 times and the same issue all 4 times.
It seems that mailman is setup correctly but when I go to the mailman url Admin link I should be able to click on the created mailman list to finish. It looks like the web browser is trying to open the link it adds it's list name to the url string, grinds away for a second and stops. I checked the popup blocker on my browser to see if that was the problem.
Is there a TCP or UDP port that should be opened for mailman? All the pop/smtp/imap ports on my firewall are open.
