Hi all. I have a problem with one user. His quota is upper of real

Well, du -h doesn't necessarily match the quota. For example if the
user has copied the same message multiple times, du counts its disk
space only once. I'd guess that's the problem. Perhaps there's a 1 MB
mail that's been copied 80 times or something?

Maybe use something like "ls -l" for each cur/ directory and count the
"total" numbers together. That should give something closer to the
Maildir++ quota.
