using shared mailboxes

[Aleksandar Milivojevic]

I've setup shared mailbox using examples from "Managing IMAP" book.  It 
works, except that I have no idea how to append messages to this mailbox.

I've created the mailbox as follows:

localhost> cm user.foo
localhost> cm user.foo.bar
localhost> sam user.foo.bar anyone lr
localhost> sam user.foo.bar someuser p

Using Mozilla Thunderbird (properties->sharing), I can see that I have 
read, lookup and post rights on user.foo.bar mailbox when I'm logged in 
as someuser.  But, how to actually post anything into that mailbox?

If I just send email to foo+bar at somewhere.com (with 
someuser at somewhere.com), the message ends up in user.foo, not in 
user.foo.bar.  I'd kind of expected this (sender's address is easlly 
forged, so it wouldn't make sense to use it for this purpose).

If I try to select a message from my mailbox and copy it over to 
user.foo.bar using Thunderbird's "Copy To" menu command, it doesn't work 
either.  Thunderbird displays folders up to user.foo, and than it 
presents me with empty list of folders (it doesn't even displays 
user.foo.bar).  Drag&Drop doesn't work either.  And there's no option of 
composing the message directly into user.foo.bar.

Is this bug in Thuderbird, or are things supposed to work in some 
different way?  How?
