Greetings, I have a detail when looking at the size of the users' quota, in iredadmin-pro it shows one size, in roundcubemail it shows another size, the percentage is the same but the value in MB is different.

root@mail1:# doveadm quota get -u myuser96@mydomain
Quota name Type      Value   Limit                                                                                       %
