Thanks all. It looks like Thunderbird will do what I need.

Multiple PCs
If each user has their own PC you could store the profile on a file share. Thunderbird supports both drive letters and UNC pathnames when specifying the location of a profile. The file server will lock access to the files as needed to prevent corruption when multiple users access the profile at the same time. However, due to the way Thunderbird works there are problems having multiple users access the same folder at the same time. It works best if all of the messages in that folder have already been read and each user just reads messages in that folder.
Most file sharing software only allows one user to have write access to a file at a time. Thunderbird uses a separate file to store the messages for each folder and another file to cache the folder listing information for that folder. This means every time somebody reads a new message, changes a label or replies to a message it will lock one or both of those files. This makes it awkward for multiple users to access the same folder at the same time. Thunderbird also writes to the prefs.js file whenever it exits, even if you didn't change any settings.
Some users appear not to have any problems sharing a profile on a file share, while others find it unusable. This appears to be due to differences in how they share the profile. Its best suited for multiple users who don't access the profile at the same time or a single user who uses multiple PCs.
It sounds easy enough, especially since I'll be the only user. We'll see if there are any gotchas....
Naturally, there are some Windows-isms that can cause problems when accessing the profile from Linux: http://web.archive.o...d/share_mail.html
I'll report back if/when I get this working.
Cheers,
Scott.
