Software quotas are also problematic only if user has direct access to the system. I don't see a reason why they would otherwise be bad. As I said in my reply to Matthias Andree, all the users are virtual, so

Dovecot will most likely support soft quotas within few months. It will also support different backends (maildir++, sql). To return to my original question, would it work to implement quotas now with Maildrop, even though Dovecot doesn't support it, or should I just wait until version 1.0 (or whenever quotas are supported) is released? My thinking is that even if Dovecot doesn't support quotas, I can at least control what amount of mail arrives for the user, and I believe I saw something that said that Maildrop will recalculate the percentage of the quota filled on a regular basis if there is something (like Dovecot) fiddling with the mail but not changing the percentage. But if I'm wrong, and this is just going to hopelessly mess things up, I'd like to know. :Peter
