Yes I use "unixhierarchysep: 1"


$ cat /etc/imapd.conf | grep unixhierarchysep
unixhierarchysep: yes

I found this funny discovery.


Running "cm user.satimiscyrus" it creates "user.satimiscyrus
(\HasNoChildren)", with no mailbox for this user created.


# locate satimiscyru
# find / -name satimiscyrus
both having no printout.


Neither can I login SquirrelMail nor emails can be received, all
rejected.


Running "cm user/satimiscyrus" it creates "user/satimiscyrus
(\HasNoChildren)", with mailboxes for this user created.


# find / -name satimiscyrus
/var/spool/cyrus/mail/s/user/satimiscyrus


# ls -l /var/spool/cyrus/mail/s/user/satimiscyrus
total 16
-rw------- 1 cyrus mail 1503 2008-06-15 08:50 13.
-rw------- 1 cyrus mail 1116 2008-06-15 14:38 cyrus.cache
-rw------- 1 cyrus mail  158 2008-06-09 16:35 cyrus.header
-rw------- 1 cyrus mail  136 2008-06-15 14:38 cyrus.index


# ls -ld /var/spool/cyrus/mail/s/user/satimiscyrus
drwx------ 2 cyrus mail 4096 2008-06-15 14:38
/var/spool/cyrus/mail/s/user/satimiscyrus


I can login SquirrelMail sending and receiving emails.  But the email
sent can't be saved on Inbox.sent.  Nor incoming emails received can be
deleted on Inbox.


It took me half day to find it out.

I already solved the authentication problem by adding a line 
"sasl_saslauthd_path: /var/spool/postfix/var/run/saslauthd/mux" on
/etc/imapd.conf


I don't know why it was missed.

Login cyrus
then ran;
cyradm localhost
cm user/aaa

to create mail boxes for user "aaa".  


If running "cm user.aaa", no mail box will be created.

# find / -name aaa
can't find it.

I did the same only adding the option "-m" on running;

# useradd -m aaa
to create aaa's home directory.


Now mail boxes are created but the user has no previlage using them.
