Dovecot quota

Witam.

Nie rozumiem  jak działa obsługa quoty przez dovecot'a.
Przykładowa konfiguracja  z dokumentacji dovecota jest np. pod adresem:
http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL?action=show&redirect=DovecotLDAPostfixAdminMySQL
Wszędzie jest wiele przykładów, ale nie znalazłem informacji jak działa ten mechanizm.

Powiedzmy że w bazie są użytkownicy, quota i domeny, skrzynki są w formacie Maildir na dysku.
Za każdym  razem jak przychodzi i wychodzi wiadomość dovectot musi robić update w bazie.
A jak zadziała ten mechanizm jak np. skopiuje wiadomości z jednej skrzynki do drugiej z palca?

Re: Dovecot quota

Tutaj Quota działa:

}

Przy czym z Qmailem i Vpopmailem, cala quota opiera się o plik

Kod:

/partycja/domena.tld/user/.maildir/maildirsize

w szkrzynce imap, wypełnia ją vpopmail, dovecot honoruje.

Z Postfixem to działa, ale skrzynki były zakładane przez Vpopmaila.
Postfix u mnie doręcza pocztę poprzez dovecot-LMTP

W końcu sposób działania skrzynki iMAP jest opisany w RFC.
