[Dovecot] Dovecot problem after last Debian sid update

[Paul Scott]

Hi All,

After upgrading dovecot for sid Thunderbird no longer displays the
contents of any emails

I have had a working IMAP setup for as much as a year even though I
don't understand dovecot configuration well enough to know how I got it
to go in the first place.

Here is the output of dovecot -n

# 1.1.11: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.26-1-vserver-686 i686 Debian 5.0
log_timestamp: %Y-%m-%d %H:%M:%S
disable_plaintext_auth: no
login_dir: /var/run/dovecot/login
login_executable: /usr/lib/dovecot/imap-login
mail_location: ~/Maildir
auth default:
  passdb:
    driver: passwd-file
    args: /etc/passwd.dovecot
  userdb:
    driver: passwd


TIA for any clues as what to do next.
