Summary Module Information
Last updated March 2020
In this table all modules are listed alphabetically with a brief description. Singleton and deprecated modules are identified. If a singleton module is followed by a version number, that number identifies when that module became a singleton. The Auto column indicates whether a module is loaded automatically as required. Note: this applies only to modules in version 3.x. The Type column indicates the MTA type of a given option. Options of type na do not directly apply to either a sending or receiving MTA. The Cluster column indicates whether a module is cluster-specific. The "valid" column indicates whether a module is a validation module.
