How to limit incoming connections for Sun Messaging Server

In the environment where the American bank operates, the same instance of Sun Messaging Server is to be utilized by a number of applications. e.g. Feedback application (online feedback form on their website), Broadcasting application (marketing purpose).

The bank considers the Feedback application as the most important. Definitely, customer service is very important.! That's what I always preach as well.

 

The Broadcasting application is used by the Marketing department in 10 counties around the Asia Pacific region. There will be days when more than 3-5 countries need to broadcast emails. Each country might send out around 100,000 - 200,000 emails. Sometimes, this happens at the same day around the same time.

When this happens, the delivery of feedback emails will be affected since both applications utilized the same shared resource. 

They ask for my opinion. My reply below:  

To ensure “fair sharing” of messaging service, it is sometimes necessary to limit the number of messages to be handled by the Messaging Server from a certain application (e.g. Broadcasting Application). This will ensure other applications have equal chances of sending out messages via the same Messaging Server. Metermaid comes in handy.
