yes. From the imapd.conf manpage:

       sharedprefix: Shared Folders
            If using the alternate IMAP namespace, the prefix for  the 
shared
            namespace.    The   hierarchy   delimiter  will  be 
automatically
            appended.

That's correct. If no "sharedprefix" is set, Share Folders aka Bulletin 
Boards are create without any prefix. If you set the prefix to "bb" you get 
names such as "bb.bulletinboard".

We're not really using them, but we have a few. I created them with cyradm 
like this:

cm betrieb-aktuell

This is the ACL we're using:

betrieb-aktuell:
  owner lrswipcda
  anyone lrsp

Sure, if the ACL allows it.

I don't know about postfix. With sendmail all names have to be lowercase. 
I'm also not sure about the prefix, so let's suppose the name were just 
"mybulletinboard". Then you would address that folder like this: 
+mybulletinboard at ...
