Last updated on SEPTEMBER 14, 2016

Applies to:

Sun Java System Messaging Server - Version: 5.2 to 5.2 - Release: 5.2 to 5.2
All Platforms

Symptoms

By default, Sun ONE Messaging Server 5.x does not allow relaying thanks to the ORIG_SEND_ACCESS table in the mappings file. But because of the source route adressing that the server uses internally to route messages, some messages may get through in special circumstances.
