I've recently installed dovecot (0.99.8.1) from the Debian/woody backport at 'deb http://src.braincells.com/debian woody/'

Previously, all mail have been delivered to mbox'es in ~/Mail by exim/procmail -- ~/Mail/inbox being my main mailbox.

Whenever I attempt to connect with an IMAP client, the connection is closed and the following error is reported in /var/log/syslog:

imap-login: Login: dk [192.168.0.2]
imap(dk): Unknown client workaround: outlook-idle^I###
dovecot: child 17653 (imap) returned error 89

What does error 89 signify?

My current configuration is: (non-comment lines only)

imap_listen = 192.168.0.2
imaps_listen = *
login = imap
login = pop3
verbose_proctitle = yes
client_workarounds = oe6-fetch-no-newmail outlook-idle
mailbox_check_interval = 60
auth = default
auth_mechanisms = plain
auth_userdb = passwd
auth_passdb = pam
auth_user = root
auth_verbose = yes

In my confusion, I blindly tried changing settings, attempting to get a different error message at least. :-)

These are the settings I have tried, without success:

default_mail_env = mbox:~/Mail:INBOX=~/Mail/inbox
mail_full_filesystem_access = yes
mbox_locks = fcntl
auth_passdb = shadow

There is no subdirectories in ~/Mail, neither visible nor hidden.

I did try to read the docs, and I did browse the mailing list archives, but either I missed something or it is not there. Any ideas?

Thank you, David Knudsen
