Mail & Deploy supports the implementation of a development environment that consists of a test system and a production system.
The test system is an installation of Mail & Deploy Server on a server that may be used to test new reports (see Reports) and tasks (see Tasks). The production system is an installation of Mail & Deploy Server on a server that is different from the one of the test system and contains the actual production environment.
For each repository, there is one copy in the test system and one copy in the production system. New reports and tasks or changes to reports and tasks can be first done and tested on the test system and then be published (see Publishing) to the production system if all tests succeed.
