Corporate Email Hosting on Sun Java System Messaging Server

Our company provides Corporate Email Hosting (OpenMail.SG - Enterprise Messaging Server). It is a hosted environment with backend being Sun Java System Messaging Server.

We used to be running Postfix and Squirrelmail as the web interface. A decision was made a year ago to make the switch considering the fact that:
  • Our company (Azimuth Labs) has been Sun's Partner for the past 5 years focusing on Portal, Messaging, and Identity
  • We have architect and deployed numerous Messaging systems in the Asia-South region
  • We are already the domain expert - so why not?

Besides, we already have a team of support engineers providing Sun Java System Messaging support to one of the government-link company ("GLC") in Singapore.

  • So, why do we need the same team to support 2 different platforms? It does not support economy of scales.


After the switch, we are getting positive feedbacks from customers, as well as, our own support engineers.

Customers' feedback

  • The web interfaces have improved by a lot (There are 2 interfaces to choose from - Convergence or Communications Express)
  • Finding co-workers via Corporate Address Book is easier
  • Premium customers have integrated Calendar support (based on again Sun Java System Calendar Server). They can set events and email notifications.

Support Enginners' feedback

  • Configuring vacation message autoresponder in Squirrelmail was a pain. This feature is available out-of-the-box in Sun Java System Messaging Server.
  • Managing domains and users is easier now with Sun Java System Delegated Administrator - a convenient web interface for our backend engineers
  • The team is now more focus since they no longer need to support Postifx/SqurrielMail

SideTrack: I'm keeping my fingers crossed that Oracle will not throw away Sun Convergence. Convergence, by far, is one of the better web interfaces I have come across from Sun. On the ground, it does create a "WOW" impression when we present Convergence to customers.
