[Dovecot] 1.0.10 - Can deliver get quotas from users maildirsize?

Hello...

I'm experimenting with controlling users quota by manipulation the maildirsize files in virtual users (LDAP) homedirs (Is this OK?). This works with IMAP, but deliver via postfix delivers mail to users even if they are over quota. I would like to reject new mails in this case.

Any ideas?

Thanks, Tobias
