I recentry upgraded a Lotus Domino server to 8.5 and installed Lotus Notes Traveler 8.5 – and the upgraded Domino server was up and running with Traveler loaded within two hours! Potential mobile clients could then connect and install the provided Traveler client software. However, I do not own a Nokia S60 device or a Windows Mobile device which are the devices currently supported by Traveler. I own an iPhone and eagerly await that an upcoming release of Traveler will support ActiveSync and thereby support push mail for the iPhone.
Lotus Notes Traveler was introduced with the Domino 8.0.1 release and is and now in release 8.5. Traveler is push mail for Lotus Domino and other solutions in the push mail area include Excitor with DME, Visto, Funambol, and of course Blackberry with their Enterprise Server product.
Documentation for Traveler 8.5 is available and the following presentation is a good introduction to the features of the Traveler 8.5 release:
