cannot view mail tree with COURIER server

[steph@ne]

I have installed the latest version of OX (6.18.0 Rev7) and all seem fine including IMAP authentication. One last issue: I cannot see the email tree of the COURIER IMAP server. and I just have INBOX folder.

There is a message in the log file:

Hi,

this indicates a error at the IMAP Server. The message "A241 NO [ALERT] STATUS" is returned by Courier when getting subfolders. Perhaps some internal IMAP server error? You might check the logfiles for courier.

thanks for your fast answer. I wikk check the logs but it is a huge file :-(

very strange: no errors messages in /var/log/mail.log from IMAP server.
And it is OK for all users except myself. no french accents in the IMAP folders.
The IMAP tree is OK with squirremail and thunderbird.
I don't understand :-(
