When you export a package that is associated with a listener, information about that listener is sent with the package. However, in the case of an e-mail listener, not all the listener configuration information is sent to the destination Integration Server. Specifically, the outbound password that the e-mail listener uses to connect to the e-mail Server is not sent. As a result, when the listener on the destination Integration Server tries to connect to the e-mail server, the connection fails. Although the listener appears on the list of ports, it will not be enabled. You will also see error messages on the server console.

To enable the port, go to the Security > Ports > Edit E-mail Client Configuration Screen in the Integration Server Administrator and update the Password field to specify the password needed to connect to the e-mail server.

If you export a package that is associated with an e-mail listener from a 6.5 Integration Server to a pre-6.5 Integration Server, the e-mail listener will not be replicated at all. You must manually reconfigure the listener on the pre-6.5 Integration Server after installing the package there.
