Mailman and Zimbra

[carnold]

I am using Os Zimbra 5 beta 3. I have a webserver and a mailserver, both are different machines. I have mailman installed and a list created on the webserver. Now i would like to configure zimbra for mailman. I have been reading this but this thread seems to be when you install mailman on the zimbra system; mine is not setup this way. So my questions are what do i need to do to make zimbra and mailman integrate? I did try parts of this thread but when i modified the postfix main.cf file, i was not able to send email. Thanks for any help

I read here that this would change with zimbra 5 and that is what i am running. Will mailman integrate with zimbra on zimbra 5?
