Thanks for the info. What I am looking for is an IMAP client, ideally with off-line capability, hence my interest in Mozilla, not so much for the browser and the mail client. Any ideas?
Having discovered that flashing the ROM is not so hard, I have now flashed to Open Zaurus just to see what is on offer, so I should be able to try some of the OPIE packages.
I can afford just to spend some time playing around with it as I still use my Revo Plus for what I need to do.
The bigger picture is that I am doing some things with Linux mail servers to try to put together an Open Source alternative to M$ Exchange Server. On the PC desktops I am using various clients which include SquirrelMail (because it\'s customisable), Mozilla Mail (because if can work off-line) and Outlook (because some people insist on it).
The missing piece at the moment is to be able to sync the PDA with the Linux mail (SquirrelMail) system. A good IMAP client would be a start and then if might just be a case of getting the PDA Calendar to play nicely with SquirrelMail Calendars.
