Ok, I've copied Sam in this email, so that he can answer
authoritatively. Sam could you please explain the following 2 things:

1. In the file maildir/maildirquota.h, I see:

struct maildirquota {
        off_t nbytes;   /* # of bytes, 0 - unlimited */
        int nmessages;  /* # of messages, 0 - unlimited */
};


To me, that means that a value of 0 is to be interpreted as "no quota
limit". Please correct me if I am wrong.

2. Second, if I place the value "1000000S" in my maildirsize file, and
go to read my email with say sqwebmail, I see the text "You are using
x% of your quota". If I then place "0S" in the maildirsize file, I
don't get any text telling me about my quota usage, meaning that no
quotas are being enforced. So again, I am correct in interpreting that
a value of 0 means no quota enforcement. Please correct me if I am
wrong.
