[Dovecot] How to interpret quota log entries?

[Pascal Volk]

Hi,

I've configured a global quota rule, with low limits for testing
purpose: quota_rule = *:storage=10M:messages=10

Why is the percentage value always 0?
What does 'enforcing' mean in this context? Is it not only relevant if
one uses fs-quota?

Jan 21 17:54:44 vh3 dovecot: IMAP(u...@test.tld): Quota root: name=user 
backend=dict args=:proxy::quotadict
Jan 21 17:54:44 vh3 dovecot: IMAP(u...@test.tld): dict quota: 
user=u...@test.tld, uri=proxy::quotadict, enforcing=0
Jan 21 17:54:44 vh3 dovecot: IMAP(u...@test.tld): Quota rule: root=user 
mailbox=* bytes=10485760 (0%) messages=10 (0%)
Jan 21 17:54:49 vh3 deliver(u...@test.tld): Quota root: name=user backend=dict 
args=:proxy::quotadict
Jan 21 17:54:49 vh3 deliver(u...@test.tld): dict quota: user=u...@test.tld, 
uri=proxy::quotadict, enforcing=0
Jan 21 17:54:49 vh3 deliver(u...@test.tld): Quota rule: root=user mailbox=* 
bytes=10485760 (0%) messages=10 (0%)

The current quota usage for u...@test.tld:

        mailsys=# SELECT * FROM quota WHERE username = 'u...@test.tld';
           username    |      path      | current 
        ---------------+----------------+---------
         u...@test.tld | quota/storage  | 9977225
         u...@test.tld | quota/messages |       4
