About a month ago I was thinking about various possible ways to implement quotas on Maildir mailboxes without using filesystem-based quotas. In some situations, like virtual domains, filesystem quotas will not work. I've played with my original idea, and came up with a slightly different way to potentially implement something like this. This one should be much simpler to implement and use. Many thanks to the few who provided feedback the first time around: http://www.concentric.net/~mrsam/maildirpp.html
