Mail sent from Lotus Notes Traveler mobile devices is first processed by the Lotus Notes Traveler server and then placed into a Lotus Domino mail box database. By default, the mail box database used is the mail.box database located on the mobile user's Domino mail server. If the database mail.box is not found, the Lotus Notes Traveler server will search for mail1.box through mail10.box until one is found. Once the mail is deposited into a mail box database, normal Domino mail routing will process the mail and route to the appropriate destination.

Starting with Lotus Notes Traveler 8.5.3.1, it is possible to override the outbound Domino mail server that Lotus Traveler is using by providing a list of alternate server addresses. This is accomplished by setting a configuration variable on the Notes Traveler server. For IBM Notes Traveler servers that are version 8.5.3.1 or later, but prior to version 8.5.3.100, set this value by editing the file \traveler\cfg\NTSConfig.xml. Using a text editor, add the following line to the properties for the component called "TrueSyncServer":

<PROPERTY NAME="OUTBOX_MAIL_SERVERS" VALUE="server_list"/> 

If the Notes Traveler server version is 8.5.3.100 or later, all configuration settings are made using the Domino notes.ini file. Either edit this file directly or use the Domino console command set config NTS_OUTBOX_MAIL_SERVERS=server_list.

NTS_OUTBOX_MAIL_SERVERS=server_list 

The value server_list is one or more comma separated strings representing the name of a Domino server in your network that contains a mail box database. Server names in the list should be in the form Server/Domain, though dotted decimal names are also accepted. The server names can include the local Domino server that Lotus Notes Traveler is using or they can be remote mail servers. Once the configuration change is made, restart the Lotus Notes Traveler task as this setting is not dynamically discovered. When the Lotus Notes Traveler server detects this override setting, it will attempt to deliver outbound mail to the first server in this server list. If this server is not available, it will continue down the list until it finds an available server. If no servers are available, the mail will not be sent and an error will be returned to the mobile device attempting to send the message.

When applying this override, make sure that the mail.box database is present on the remote mail server and that this server allows access from the Lotus Notes Traveler server. The Domino trace command can be used to verify server to server communication is possible, and you should test that mail routing is working using a mobile device once configured.
