Hello,
when looking  inside /var/log/dovecot.log , i can see quota warning messages, followed by  quota grace, which are not reasonable at all.
I checked actual user  quota with doveadm quota get -u ntpr@someserver.sk and value of messages and storage is zero, or almost zero, not even near the  quota numbers.

i would not like , that my users will not get emails rejected because of this.
thank you
