+1 on quotas; they are virtuous even if capacity isn't a constraint -
they force users to manage their data.

Regarding sent/trash/SPAM Cyrus IMAPd provides an "expire" annotation
that can be applied to folders that will expire messages from the
folders older than X number of days [on the server side, user doesn't
have to login for this to happen].  For example we expire sent-mail at
365 days, trash at 45 days, and SPAM at 14 days.  This helps quite a bit
against lazy-user-syndrome.
