First Cyrus Install question: "Mailbox does not exist"

[John N. Brahy]

"Mailbox does not exist"

Ok, I've been hacking at this install for a while and I can't get past
this error. I am able to create other folders without a problem but I
can't get incoming mail. This user has a directory in the user
directory:

# find /var/imap/user/
/var/imap/user/
/var/imap/user/j
/var/imap/user/j/jbrahy.sub
/var/imap/user/j/jbrahy.seen

And here are the contents of my configuration file:

# cat /etc/imapd.conf
configdirectory: /var/imap
partition-default: /var/imap
sievedir: /var/imap/sieve
admins: admin jbrahy
allowanonymouslogin: no
autocreatequota: 10240
reject8bit: no
quotawarn: 90

poptimeout: 10

sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN LOGIN
lmtp_overquota_perm_failure: no
unixhierarchysep: no
virtdomains: userid

loginrealms: callu.com
tls_cert_file: /etc/ssl/server.crt
tls_key_file: /etc/ssl/private/server.key
tls_ca_file: /etc/ssl/private/server.csr

I'm running OpenBSD 3.8 w/ Cyrus and these packages are installed:
# pkg_info -a | grep cyrus
cyrus-imapd-2.2.12  Cyrus IMAP server
cyrus-sasl-2.1.20p4 RFC 2222 SASL (Simple Authentication and Security
Layer)

Where else can I look? And what should I change?

Thank you,

John
