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.
