Hi guys -
So what can we use instead? We've just had 2 days downtime because 
Dovecot was using 100% of the disk. As reported above - every action on 
a user mailbox seems to lstat every file in the user's home.

So we've disabled quota completely and these millions of lstats have 
stopped.

We're running virtual users (all under a vmail system user) so fs quota 
is not workable. What do you recommend for a Maildir?

This is bad enough to almost work having Dovecot throw a:
WARNING: dirsize not recommended with Maildir format.

Best wishes,
Daniel
