I've just configured Mailman to run on a box that uses the Netscape servers (main, news, LDAP). It's doable and workable, if anyone is interested I can make a writeup.
Two problems (apart from the ones that have to do with the Netscape software):
entering ..../mailman/admin/list, I get the password box - whatever I do, I'm bounced back to .../mailman/admin. When inspecting the HTML, ACTION is set to "/mailman/admin" instead of "/mailman/admin/list".
duplicate Sender header. Dunnow whether it should've been stripped beforehand, but adding a "del msg['sender']" at line 121 of GatewayManager.py seems to do the trick.
Last remark: Great stuff! I'll be replacing my Majordomo setup at home ASAP :-)
