Dovecot and Mailman should be mostly independent of each other, while both depend crucially on Postfix. The first thing to do is to find the log files for each application, and test that mail works for all combinations of inside and outside the system (and often "outside" has to be divided into "your domain" and "the rest of the Internet"), to and from. If Dovecot isn't working, you still should be able to see mail flowing in the Postfix logs, and possibly learn something about its status using the mailq tool. Next work on being able to read and perhaps submit mail via Dovecot. Finally, do the Mailman configuration. Testing Dovecot or Mailman in the absence of a working Postfix is going to be hard for you, I guess. It's not impossible, but it requires some knowledge of internals of each program, and a fair amount of confidence with Unix tools like pipes and netcat. Much easier to learn to read Postfix's logs to determine when the problem is with one of the (non- ;-) cooperating applications, and when it's Postfix. It would help if you describe the symptoms, although perhaps the best thing we can do is direct you to a Postfix or Dovecot channel.
