Setting Postfix + Courier + Cyrus: cannot find user dir on authentication
 

Hi All,
I am trying to adapt a tutorial for setting a mail server in Arch Linux [1] to Debian. I finished the step of PostfixAdmin, and I perfectly can send e-mails from it and add users and domains to the database. Looking at /home/vmail, I also checked that I can receive e-mails. Before setting up Rouncube, I wanted to try accessing with Thunderbird, but I am getting the message of Incorrect username or password.

Looking at the logs, on mail.log I can see:Jan *3 00:32:52 cub3 imapd: Connection, ip=[::ffff:80.35.195.218]Jan *3 00:32:53 cub3 imapd: chdir Maildir: No such file or directory
Jan *3 00:32:53 cub3 imapd: sachiel@cub3.net: No such file or directory
But:# ls /home/vmail/sachiel@cub3.net
# ls /home/vmail/sachiel@cub3.net/cur *new *tmp# ls /home/vmail/sachiel@cub3.net/new/1325457494.Vca00I4f096M587089.cub3 *1325457546.Vca00I4f099M501611.cub3 *1325471089.Vca00I4f78fM130501.cub3

So the directories exist... I've rechecked the config files several times (even on*different*days, as resting is always good :P), and googling around, but no luck about what is wrong. Any advice about where to look for it is appreciated.

Regards,Sergi

I have no previous experience with Courier, but the above message seems
to indicate Courier can't find the proper place where messages are being
dropped.

Mmm... isn't a parent "/Maildir" folder required? :-?

I mean, something like: "/$HOME/vmail/$user/Maildir/cur|new|tmp"

I would also check where is the Courier variable for the stored mailboxes
pointing to.

I used this to set up Courier
http://edin.no-ip.com/blog/hswong3i/exim4-courier-ssl-debian-etch-mini-howto

Which contains this:
If you have an existing user account without Maildir under home
directory, run the following command:

maildirmake ~/Maildir

In the setup I use, the emails are not stored under each local user's
home, but in /home/vmail/user@domain/ . The Maildir hierarchy is
reproduced inside this directory, as I showed on the first message.

Sergi, "chdir Maildir: No such file or directory" message seems to mean
the server is trying to "go" to that directory and is not found, because
it does not exist.

http://www.courier-mta.org/imapd.html

"(...) The last daisy-chained command is imapd, which is the actual IMAP
server, which is started from the logged-in account's home directory. The
sole argument to imapd is the pathname to the default IMAP mailbox, which
is usually ./Maildir. Some authentication modules are capable of
specifying a different filename, by setting the MAILDIR environment
variable."

I would start by discarding a problem with a bad folder structure
required by Courier.

Yes, you're right. What puzzles me is that on /etc/courier/authmysqlrc
I have specified:

MYSQL_HOME_FIELD "/home/vmail"

and

# This is an optional field, and can be used to specify an arbitrary
# location of the maildir for the account, which normally defaults to
# $HOME/Maildir (where $HOME is read from MYSQL_HOME_FIELD).
#
# You still need to provide a MYSQL_HOME_FIELD, even if you uncomment this
# out.
#
MYSQL_MAILDIR_FIELD maildir

Being maildir a field on the database with the content: user@domain,
therefore imapd should use /home/vmail/user@domain/ as Maildir . For
some reason is ignoring it?

Sergi... as I see, "/Maildir" is a folder, it has to exist in your path
or you have to configure Courier to look into another different place,
which is not the case :-)

I can be wrong because I have not used Courier before, but this can be
easily tried, just create a new "test" account at:

/home/vmail/Maildir/test@cub3.net/

Restart the daemons, send a message to that account ("To: test@cub3.net"),
try to login and review the logs.

>From what I understand from the documentation, a maildir is actually a
hierachy of subfolders (./new, ./cur, ./tmp, etc), which is usually
located at /home/user/Maildir. In the setup I'm trying, this hierarchy
hang from /home/vmail/user@domain/ . Actaully, postfix creates this
architecture of folders when I set-up a mail user and send an e-mail
to it. With the config files I posted before, courier should look at
these folders, but he is looking in another place... :S

Ok, I finally found what was wrong.

On authmysqlrc, MYSQL_MAILDIR_FIELD must be the full path to the
maildir, not the relative path according to MYSQL_HOME_FIELD.

So, instead of
MYSQL_HOME_FIELD "/home/vmail"
MYSQL_MAILDIR_FIELD mail

It must be:
MYSQL_HOME_FIELD "/home/vmail"
MYSQL_MAILDIR_FIELD concat("/home/vmail/",mail)

Thank you for the guidance.
