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.

0 0Could 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

Locking? You mean it allowed user to exceed quota? mail_debug=yes could log something useful about what's going on.
