Do you still have the files? You forgot to send the
dovecot.index.log file. Also perhaps dovecot.index.cache could help
when figuring this out (but it contains message headers so you may
not want to send it to this mailing list at least).

Hi, I still have them. I sent both dovecot.index and dovecot.index.log the last time, but
now I've also added the cache file in a tgz.

Oh. I guess that's why Mail.app showed some weird input in the mail.
Anyway fixed now: http://hg.dovecot.org/dovecot-1.1/rev/d674c05d725d
