I'm reasonably confident that I have mail working on the TiBook now. But for a while there, I didn't. In fact, for a while there I had a mailing loop that was causing bounce messages. Luckily, I didn't actually lose the messages, so the upcoming summary should still be reasonably complete, but I'm worried that so many bounces may have got me auto unsubbed from some mailing lists...
Anyway, if you've tried to send me mail and got a bounce, you probably won't need to resend, but it's probably a good idea to don belt and braces and resend it.
Sorry for any inconvenience caused.
