Newbie Q's: Mailbox not found

[Jon Drukman]

ok i'm just getting started, and i finally got authentication working (i 
think).  however now i can't get mailboxes to accept mail.  all mail 
bounces with "550 Mailbox unknown" --

Sep 27 10:33:21 rs2 postfix/lmtp[74804]: 43E39269ED: to=<jsd at rs2.spot.com>, 
relay=/var/imap/socket/lmtp[/var/imap/socket/lmtp], delay=0, status=bounced 
(host /var/imap/socket/lmtp[/var/imap/socket/lmtp] said: 550-Mailbox 
unknown.  Either there is no mailbox associated with this 550-name or you 
do not have authorization to see it. 550 5.1.1 User unknown)


# ./deliver jsd
jsd: Mailbox does not exist
# cyradm --user cyrus localhost
