The port that Mailman connects to the upstream SMTP server is already configurable, so I don't think we need to do the probing and caching Ian describes. It looks fairly easy to add a username/password pair for the SMTP connection, and to call .login() if they're set. So I'll add those. It probably would not be difficult to add keyfile and certfile configuration variables and call SMTP_SSL() when those are given. I'll look at adding that too. ** Changed in: mailman Status: Triaged => In Progress ** Changed in: mailman Assignee: (unassigned) => Barry Warsaw (barry) -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/490044 Title: Implement SMTP AUTH in Mailman 3
