Mailbox size calculated wrong

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Plesk: Plesk Obsidian 18.0.76 Update 4 - Web Host Edition
OS (lsb_release -d): Description: Ubuntu 20.04.6 LTS

PROBLEM DESCRIPTION

The calculation of the mailboxes size is calculated wrong. Plesk shows me 5.93 GB (value in table psa.disk_usage, column mailboxes is 6370893824). But size on disk (du -sh --apparent-size /var/qmail/mailnames/<domain>/) is
2.6G /var/qmail/mailnames/<domain>/. I have no mailinglists active (is also 0 in column maillists).

STEPS TO REPRODUCE

# plesk repair mail
# /usr/local/psa/admin/sbin/statistics --calculate-one --domain-name=<domain>

Value in table psa.disk_usage, column mailboxes is wrong (also at Plesk panel).

# plesk repair installation -y
# /usr/local/psa/admin/sbin/statistics --calculate-one --domain-name=<domain>

Value in table psa.disk_usage, column mailboxes is wrong (also at Plesk panel).

# plesk repair mail <mail@domain> (for all the mailboxes of the domain)
# /usr/local/psa/admin/sbin/statistics --calculate-one --domain-name=<domain>

Value in table psa.disk_usage, column mailboxes is wrong (also at Plesk panel).

# rm ./*/Maildir/maildirsize
# doveadm quota recalc -u <mail@domain> (for all the mailboxes of the domain)
# doveadm quota get -u mail@domain (these values are correct!)
# /usr/local/psa/admin/sbin/statistics --calculate-one --domain-name=<domain>

Value in table psa.disk_usage, column mailboxes is wrong (also at Plesk panel).

ACTUAL RESULT

The value is calculated wrong. Since ~3 weeks(?)

EXPECTED RESULT

Value in table psa.disk_usage for the table musst be the same (or nearly the same) like du -sh --apparent-size /var/qmail/mailnames/<domain>/

ANY ADDITIONAL INFORMATION

I'm a skilled it nerd, so don't hesitate to ask me any further questions if you need more information

Hello, @Webbenny . Could you please execute the following command and provide us with the output:

doveadm mailbox list -u mail@domain

Thank you for your reply. I guess your refer to the mixed-INBOX-folder article (https://support.plesk.com/hc/en-us/...Plesk-UI-differs-from-the-actual-size-on-disk). But an indication for that issue would be that the doveadm quota get -u differs from du -sch * or Plesk Mailbox details Site which is not the case. I have six mailboxes, all structures of the mailboxes look normal:

The output of doveadm quota get -u is also correct and is the same like in the details for every single mailbox in the Plesk Panel. But the total value in Plesk is wrong.
