I've received a lot of requests for the bridge we wrote to make Joomla work with mailman.   Here it is!

It now supports Joomla 1.5 when running in Legacy Mode.

The goal of this component was to first get the logged in user's email address, then get a list of public mailman mailing lists that they could subscribe to.  It lists all publicly available lists, with a preselected button based on whether or not they're already subscribed to that given list.  It allows them to subscribe via regular or digest mode.

They select what list(s) they want, and what mode they want, and click "Subscribe," and magic happens.  They get subscribed, the web page tells them what happened, and they get an email telling them what happened.

Download the component for Joomla 1.0 here .

Download the component for Joomla 1.5 here .  (The 1.5 version is new, so please let me know how it works.)

If you want to see how it works, you're welcome to sign up to my site, http://www.backupcentral.com/, and log in.  You'll then see a menu item called "Forums & Mailing Lists -> Mailing Lists."  Click that and you'll see how it works.  Feel free to subscribe to and post to the mailing list called Testy.

Thank you very much to Stefan Haller who took my raw component and created an admin interface to it.  Now you don't have to edit the mailman.php script any more! 

Here are the install instructions:

1. Install the component via standard install procedures.
2. Point your admin browser to Components -> Mailman2 -> Config, and change the five or six config variables. 

3. Make a menu item under your user menu
   a. It should be of “Link URL” type
   b. It should point to /index.php?option=com_mailman2
   c. It should only be available to registered, logged in users
4. That's it!

FAQs:

Does this require command line access to the Mailman commands?

No.

The component is installed and I configured it in the admin screen, but when I run it, I see "Warning: Invalid argument supplied for foreach() in /home/accname/public_html/components/com_mailman2/mailman2.php on line 203"  What's up with that?

So far everyone who has had this error has not put the right values in the configuration screen.  The most common misconfiguration mistake is to leave the http:// in the domain name you're using to admin Mailman.  If your domain admin interface is http://mydomain.com, you should enter just domain.com as the value for the admin domain.

Good luck.  I’d love to see how well you get on with it.

We're still open to suggestions and welcome anyone who would like to contribute to the work.
