Disk quota issues

In my user accounts, the email quota total not getting showed properly

In the attached image, total email usage shown as 9.2MB while individual emails are using much bigger spaces.

How to fix?

ooo the hottest topic, since I'm waiting for this moment but unfortunately the answers will be the same "we are working on this" or watch "https://control-webpanel.com/changelog", there is nothing official from them what for many cwp users is unpleasant, I have opened this topic several times on this forum, I have also opened a ticket to CWP but nothing concrete ... This change is the most important, of course and the security part.
we are still waiting for the problem with e-mail space to be solved, to respect the hosting plan, is it so complicated to make this change?
look here, I think that's what you mean, but I'm not sure it works https://forum.centos-webpanel.com/e-mail/how-to-change-mailbox-folder-mount-point/

the calculation for the quota is wrong, you can see here discussions about this problem that will not be solved too soon

I am waiting for the solution, how long does it last?
