The idea is the Dovecot LDA would deliver the message and if this caused the mailbox to reach 100%+, add a file into the maibox say "username/Maildir/overquota". Interactions via Dovecot IMAP/POP3 that lower the mailbox usage, for example the user popping, or deleting mail from the mailbox would trigger Dovecot to unlink the file.

They appear to trigger during maildelivers say via the LDA, however IMAP 
mailbox interactions (say deleting an email or copying an email) do not 
trigger them. I ended up having this patched into the quota plugin and 
works a treat.
