difference between postuser and sharedprefix ?

Greets.

I'm for the first time playing around with shared folders under Cyrus
IMAPd 2.1.9. I have several normal user accounts up and running fine
with my config.

In the imapd.conf I see there are two options for controlling shared
folders. postuser and sharedprefix. I created a mailbox with cyradm (cm
testbox) and gave it ACL anonymous p. It gets mail just fine when I
sent to share+testbox at myhost.com

This seems to work well if I set "shareprefix: share" or if I leave
that out and set "postuser: share". So I'm confused as to what the
differences are between the two settings when they both seem to work
the same?
