Hi all, I have configured mailman and all is good except I have to manage the mailman lists and administrate it via server IP and none of the actual domain names in the link receives by email works. I have few site on my ispconfig 3 server. so when I create a list it create it and when I try to subscribe to one of the list the email also comes to my admin email with administration link for approval. but the links have http://domain.ltd/.... format and none of the links from any domains work. I have to use the server IP instead of domain.ltd to be able to see the list and actually cannot manage it well because most of the links inside the page also refers to domain.ltd. is there anything that I have to set to fix this issue?
