[Dovecot] Problem with ldap / quotas

[Nikolaos Milas]

Here is a session logged with mail_debug=yes; the mailbox has already 
exceeded quota (I set it to 100K for testing). Note that I have only 
changed IP addresses (actual ones are public) and main domain name:

No warning mail was sent, at any point, even when the last mail was 
received, which exceeded the quota.

    # ls -la /home/vmail/tester/Maildir/new

    drwx------ 2 vmail vmail  12288 Feb 22 23:07 .

And also:

    # cat /home/vmail/tester/Maildir/maildirsize
    102400S
    0 0

Could this behavior be related to the MTA? Must we also configure quotas 
in Postfix (with VDA) for things to run correctly? (Note that I am 
forced to set (in Postfix) virtual_mailbox_limit = 0, because the max 
acceptable value of this parameter is 2G and in Dovecot I define mailbox 
limits of 4G. I haven't yet set any VDA parameters.)

Thanks,
Nick
