The actual point is that this INBOX is _writable_. The UW-Snarf feature 
will move the mail from a non-quota /spooldir/%u into the user's 
filesystem-quota limited INBOX. When that storage becomes full, this 
copying stops, waits till there is new available space, then moves further 
mails.
So, the mail is deliviered to /spooldir/%u, and won't be bounced, because 
of "user over quota"; but the user cannot _use_ endless storage.

We have been using this UW-Imap feature, too, long time. This was on some 
Dovecot TODO-list some time ago -- I think it was called UW-slurp feature 
-- , but I don't found it in the CVS TODO file unfortunately.
I will need some work-around for this too.

See above, the spool file must be read regularily.
