Thanks, that worked great. The only part I'm still trying to figure out
is to find in which group the mail is in (nnregistry is finding it, and
displaying it, but the modeline mentions the old group and not the one
where the message has been moved to). I guess this is also why
displaying the thread does not work.

For the record, here is the settings I've used:
