virtual mailbox user problem

[Feisei]

I'm running postfix and courier-imap with virtual mailboxes. For some reason my mail program won't display the mail folders for a virtual user (let's say his name is Jack).

I can send an email to Jack from another (non virtual) account just fine. When I check the actual file system I see the newly arrived email sitting there in the mail folder. So the postfix part of the mail system is working fine.

I checked my mail logs and it shows that the virtual user was authenticated succesfully by the courier authentication daemon. Seems all good to me.

But for some reason I just cannot see the email in my mail program. When I ask it (Thunderbird) to search for imap folders it just gives me an empty result.

Any idea what could be wrong?

Here are some of my config files:

/etc/courier/authdaemonrc

authmodulelist="authuserdb authpam"
authmodulelistorig="authuserdb authpam authpgsql authldap authmysql authcustom authpipe"
daemons=5

Have you told Courier where to find mail for virtual users? I don't use it so cannot help with the specifics, but given you have confirmed the mail exists in the filesystem the next logical step is to ensure Courier knows where to find it.

The following code is the result of "sudo userd -show jack"

uid=vmail
systempw=---some_encoded_password---
mail=/var/mail/vhosts/example/jack
home=/var/mail/vhosts/example/jack
gid=vmail

This makes me believe that Courier should be able to find the mail.

The directory in question is owned by the user "vmail". Here's the result of an "sudo ls -ltr /var/mail/vhosts/example/jack"

drwx--S--- 2 vmail vmail 4096 2008-11-20 16:59 tmp
drwx--S--- 2 vmail vmail 4096 2008-11-20 16:59 new
drwx--S--- 2 vmail vmail 4096 2008-11-20 16:59 cur


and "sudo ls -ltr /var/mail/vhosts/example/jack/new"

-rw------- 1 vmail vmail 862 2008-11-20 16:59 1227167971.V805I14c1b8M367300.example.com
