Installing Mailing List Manager a.k.a Mailman on Ubuntu 6.06

Mailman

Recently I Installed a mailing list manager on my mailserver. I use GNU’s mailman. It’s straightforward and simple and they have a web-based administration. I’m following this tutorial from wiki.ubuntu.com.

But unfortunately, this tutorial has some error in configuration. After a long search finally I found that, the line at /etc/mailman/mm_cfg.py should be MTA = None. But in the tutorial is MTA = Postfix.

The configuration error is not quickly found, because the mailing list is running as usual. I found this error on this situation.

My server is postfix and using virtual mail. I have a mailbox called dummybox@example.com. Then I create a lists called dummybox@lists.example.com. Everytime I send an email to dummybox@example.com, postfix try to deliver the email to mailman. And whoops, its error!

After changing MTA to None, this error dissapear.

Update #1:
I change the ┬áMTA to None on wiki.ubuntu.com. Thank God it’s wiki, a collaborated pages. So I can change the error.
