Timo Sirainen writes in response to Steve Fatula's query:
With imap_quota plugin it allows IMAP client to see how much quota is used/left. You could also enable quota warnings. And configure the quota exceeded error message.
It could also prevent the catch-22 situation I wrote about earlier whereby a filesystem out-of-space condition will result in a user not being able get themselves out of that situation, since a mailbox operation (like a delete and expunge) will not be able to create a lockfile.
Having quotas handled by the IMAP/LDA will allow extra room to handle this impasse. Disabling dotlock or using dotlock_try locking method are some other workarounds.
Don't forget these are SYSTEM users, they can get in and delete things should they need to, and can easily consume all available space completely outside of email. We already send email outside of dovecot when they approach their limit, with our custom message. It sounds like there really isn't any benefit to using the dovecot fs quota plugin in our situation. Thanks for the ideas.
