I have just installed ISPConfig 3 in a multiserver setup on CentOS servers. Among the servers are a dedicated mail server and a dedicated web server. When creating a new domain, we create DNS records pointing to the webserver as that will host the websites. The problem is that when Mailman creates a new mailing list, it sends out a welcome email using the newly created domain. Ofcourse, this doesnt work as the mailserver, and thus mailman, is a different server. How do i change the configuration so that instead of sending out mails with URLs to the customers domain, it sends out mails with URLs for the default mail server?
