How much are you backing up from "Sent" and "Trash" because nobody maintains their mail folders? A quota can be a great tool for teaching basic mail folder housekeeping.
+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.
