Ah great. I was just about to move the customer's directory to the test 
servers and try with, and without, quotas to prove it. This saves me the 
hassle.

We also have customers with one set quota for many mail accounts (under 
many domains, from LDAP, same UID) which is why file-system quotas suit 
us. But possibly dict-quotas can also handle this, I don't know. (We 
need the quota for CGI services, etc.. anyway).

Thanks for your assistance,

Lund
