Problem writing mails to Sent

Hello,

I'm using Mozilla Thunderbird and cyrus21 v.2.1.18-5.1 (at least that's
what aptitude says).

If I now try to send an email with Thunderbird, this mail gets sent, but
on copying the mail to the "Sent"-folder, Thunderbird fails with the
error "Permission denied". This didn't happen before and it came out of
nowhere, as far as I can tell.

This is a log of the IMAP conversation:

I first thought of the folder permission having changed, but this seems
not to be the case:

| bluebox:/var/spool/cyrus/mail/t/user/tinloaf# ls -l | grep ^d.*
| drwx------ 4 cyrus mail    4096 2007-09-29 18:09 admin_goerresonline
| drwx------ 3 cyrus mail    4096 2007-09-29 18:09 dev
| drwx------ 2 cyrus mail    4096 2007-09-29 17:56 Drafts
| drwx------ 2 cyrus mail    4096 2007-09-29 17:56 GMX
| drwx------ 2 cyrus mail  749568 2007-09-29 18:20 Junk
| drwx------ 8 cyrus mail    4096 2007-09-29 18:06 Listen
| drwx------ 2 cyrus mail    8192 2007-09-29 18:08 Sent
| drwx------ 2 cyrus mail   53248 2007-09-29 18:18 spambin
| drwx------ 7 cyrus mail   32768 2007-09-29 18:25 tinloaf
| drwx------ 2 cyrus mail   77824 2007-09-29 18:21 Trash

So all of the folders in my account have the same rights - and it even
works to move a message "by hand" into the Sent-Folder (i.e. dragging it
into the folder in thunderbird) - the only thing that fails is
Thunderbird moving it into the folder on sending messages.

Does anyone know what's going wrong here?

Thanks,
Lukas
