Cyrus support for multiple client access?

[Sascha Schnitzler]

Hi,

we need an IMAP-Server where multiple Clients can access one Mailbox. 
Does Cyrus provide this with the "Shared-Folder" feature?
To be more specific, this means we have a mailbox where our customer 
sends mail to and about 9 people should be able to be connected to this 
mailbox seeing the incoming messages and those, that have been answererd 
or seen). Of course, they should be able to answer, delete or move mails.

Thanks in advance,
sascha
