[Dovecot] Write-only mailboxes

Hello,

I've setup a mailbox for reporting SPAM by simply symlinking it into the 
Maildir of selected users. In order to preserve anonymity of the users I 
setup the mailbox as follows:

drwxr-xr-t 5 root    fb    4096 2007-09-05 16:18 ./
drwxr-xr-x 7 root    root  4096 2007-09-05 16:16 ../
drwx-wx-wt 2 spamd   fb   12288 2007-09-10 16:17 cur/

hence, with read permission for the spam bot only.

When Thunderbird copies mails from the same mail account into the folder, 
it seems like it tries to select the mail box afterwards, then a "Internal 
error occured. Refer to server log for more information." because of 
permission denied.

When one copies mail from yet another account into the SPAM box, no such 
message appears. I guess, Thunderbird does not try the refresh the message 
count.

Well, is there a possiblity to setup a Write-Only mailbox, with Dovecot 
v1.0.3 with the ACL plugin? Is there a working setup for write-only 
mailboxes with the ACL plugin?

Bye,
