Description:
Typically, a Sun Java System Messaging Server deployment consists of front-end and back-end services.
The front-end services enable users access to the system, while the back-end services store and provide access to data.
In the past, we've heard disputes about how to deploy the MTA on the front end: either as an entrance gateway to the system, or "behind"
an anti-spam/anti-virus service that also provides an MTA functionality.
This article describes the recommended way to deploy your MTA with respect to anti-spam/anti-virus services.
