autocreate: why do I need autocreatequota?

[Andreas Hasenack]

Regarding the autocreate patches, did I missread the documentation or do
I need to set a default quota for an user? Why can't I just give these
autocreated mailboxes unlimited quota?

My scenario is that I would like to have the INBOX mailbox created
automatically upon first successfull authentication (not on post). I'm
using cyrus-imapd 2.2.12.
