In particular, all mails sent from mailman have the port number on the end of the reply address. This causes certain mail servers to reject the messagges. A workaround is to have two web listeners, one on port 80 and one on the real port e.g. 8080. One then redirects all mailman requests on port 80 to the other port. I do this because I have to have my main web server and my mailman web server running as different users. The problem is current in 2.1.12 -- url parse (probably) cannot handle port number https://bugs.launchpad.net/bugs/265965 You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman.
