Given the unixhierarchysep option, to create a mailbox for the user 
"grail", you would issue the command "cm user/grail" within cyradm.

Check that the box exists: usually in 
/var/spool/cyrus/mail/user/grail/, there should be some files in there 
such as "cyrus.cache", "cyrus.header" and "cyrus.index". Send some 
email to that account (using SMTP to your MTA) and see what happens. If 
mail is delivered successfully, you should find a new "NNN." file in 
that directory alongside cyrus.cache and friends, eg:

[root at franklin:/var/spool/cyrus/mail/user/grail]# ls -1F

Note that the spurious mailboxes have been set up by my mail client, 
and INBOX is a symlink to ".".

If the above statements are true for your environment (mailbox is 
user/name, directory on file system contains cyrus files), you may want 
to try the "altnamespace" option. This flattens the namespace presented 
to the client, so that "INBOX" and "Trash" appear at the same level, 
rather than "Trash" appearing as "INBOX/Trash" to the client (using 
Unix hierarchy separators).

Failing all else, check the communications between your client and the 
server with a protocol analyser (eg: ethereal or tcpdump). I found many 
interesting occurrences in the communication between Cyrus and Apple's 
Mail.app - Mail.app would try to create folders before subscribing to 
them, and barf when the server tells it that the folder already exists 
(Cyrus says the create operation failed because the folder already 
exists, Mail assumes that the create operation failing was a bad thing 
and gives up).


I have learned to use the word 'impossible' with the greatest caution.
