Virtualmin on EC2 Mailman cannot be created issue

If you are getting the following error:

Failed to create virtual server : Mailman cannot be enabled unless the administration list mailman has been created.This can be done in the Mailman plugin module.

I had just came across a solution that I have tried and verified to be working from tidiar on the Amazon Web Services Developer Community. The link to the thread is http://developer.amazonwebservices.com/connect/entry.jspa?externalID=767

Click on the Network Configuration link

Click on the Network Configuration link

Click on the Hostname and DNS Client

Click on the Hostname and DNS Client

Set the Hostname field to your EC2 instance external address

Set the Hostname field to your EC2 instance external address

Thereafter just head to Virtualmin Mailman Mailing Lists in webmin, if mailman does not exist, you will find a block that looks like this:

This block will show if the default mailman is not created

This block will show if the default mailman is not created

Fill in an administration username and password. You can leave the Associate with Domain to

Hit “Create” and you are done.

You should see the following box appear on top now:

After default mailman has been created

After default mailman has been created

You can now enable mailman mailing lists when you create your virtual websites under virtualmin and you should not get the error anymore.

Again credits to tidiar on AWS forums for sharing the solution.

Back from The Actionscript Conference!

Just got back from a hectic but great day at the Actionscript Conference down at the Singapore National Library. It was a great conference with wonderful speakers like Lee Brimelow, Peter Elst, Marco Casario, Michael Plank, Prayank Swaroop, Stefan Wessels, Eksandar Gvozden (Alex) and Mohammad Khan covering topics that spanned the new flash player 10 to star wars (flash lite). Special thanks to many of them for taking the time to fly into the country. Its an amazing experience to meet these guys close up in person and talking about actionscript and everything else under the sun =)

The response to the conference was great with full attendance and we are looking forward to garnering feedback from the audience and the organising team for post-event analysis. The materials for the conference will be posted on the TAC website’s post event webpage soon so if you attended the conference, you will be able to download the materials for reference/review/practise very soon.

It was also nice to meet some of the guys from the local media, design, development agencies/houses and hearing their thoughts of flash/flex and how they are actually adopting the technologies in their day-to-day work and projects. The conference was fertile ground for networking and I guess that everyone involved would have gained a friend, a contact or some knowledge, one way or another :)

If you dropped by the conference, do leave a comment behind to say “Hi!”. Cheers!
