[Dovecot] Quota handling - v2 - updated FR

Interesting... and as long as there is only one message for each user 
(not sure how you meant 'global folder'), then this would work perfectly 
- but wouldn't the size of the virtual folder count against the quota too?

Ok, I like it...

I really like the idea of a single message for each user, that shows a 
summary of all of the messages that were rejected while they were over 
quota (Message Date/Time, Subject, size, who it was from, etc).

Maybe the global folder could be non-virtual, then a message for each 
user could be deposited there, then create either:

1. a virtual sub-folder for each user that contains only their over 
quota message, that is then merged with their Inbox, or

2. just create a link to this message in the users Inbox

I don't really care how it is implementd on the back end, as long as the 
desired result is achived

I really like that too (flagged, undeletable message), although I had 
already imagined that this message would be undeletable...

Thanks for the input.

Do you think this could all be done via the Quota Plugin?
