Web UI limitation: The WebUI README says the package is deprecated, not actively maintained or supported, and will be removed from the repository in the near future.
Configurable modules: The sample configuration includes sender and receiver modules, message and MDN storage, database tracking, and a directory resender for failed transmissions.
Database integration: The sample configuration uses an embedded H2 database by default for message tracking and allows that setting to be changed for other databases.
Health monitoring: The sample configuration includes a health-check module to monitor the OpenAS2 server, disabled by default.
