Looks right.
No warning mail was sent, at any point, even when the last mail was received, which exceeded the quota.
That log was from pop3, not from mail delivery.. It's too late by then to give any kind of warnings.
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.)
Postfix completely ignores quotas limits, warnings and everything else you've set in Dovecot! You need to be using Dovecot LDA. http://wiki.dovecot.org/LDA
