I think I have found it. I also had to disable the TaskManager module:
private static final Module PROTOCOLS = Modules.combine(
new ProtocolHandlerModule(),
new SMTPServerModule(),
// new WebAdminServerModule(),
// new DataRoutesModules(),
// new MailRepositoriesRoutesModule(),
// new MailQueueRoutesModule(),
// new NoJwtModule(),
new DefaultProcessorsConfigurationProviderModule()
// new TaskManagerModule()
);
