One thing you could do is to define a separate "lists.yourdomain.example.com" entry in your DNS, which points to the same IP address as your webserver, and has MX records in the DNS which point to your webserver. Then when mail comes in for "listname@lists.yourdomain.example.com", it automatically gets sent to where it belongs.
This would isolate the Zimbra main mail server on one machine from the mailing list server on a different machine, and allow you to easily integrate Mailman with sendmail on the webserver. That sort of thing would be covered in the Mailman installation & configuration documentation, although you'd need to choose which method of integration you would want to use.
OK, i have posfix installed and configured on the webserver (according to the mailman doc). When i send a test message to the list, i get a undeliverable notice:

If you do so, please include this problem report. You can delete your own text from the attached returned message.

I have a dns entry that points to the webserver and a mx record that points to the webserver. I just thought of something that might be causing the problem: the "real" mail server serves the virtual domain that the list also is for. It appears all mail is going to that mailserver and the user does not exist on the mailserver. Just in case, i have a skype, aim and yahoo IM account.
