[Dovecot] /var/dovecot /var/spool/mail permissions, setup help (w/ config info)

I need some help with Dovecot-1.0rc2 on Gentoo Linux. My test harness is one
Thunderbird-1.5.0.4 client, storage using legacy mbox directories ported over
from an old UW-IMAP/sendmail combo running on RHL 8.

Config is intended to be passwd/pam, plaintext login allowed (until I migrate
everyone to ssl). After this is working, postfix and dspam are to be added,
unless someone can recommend a 'dovecot of smtp' to use.

I'll tail the mail.log to illustrate the problem, then excerpt what I think are
the relevant directory and config file listings. I'm paying particular
attention to file ownership, but am loathe to just chown dovecot things unless
I know why.

Let me know if you want to see any other config info to help spot the problem.
Thanks!
