Invalid email quota in cPanel

Cpanel was showing incorrect disk space usage on all the e-mail accounts of our clients domain. The domain is hosted on the linux server and using cPanel version 11.24. Client has tried deleting the mails from the account. However, the disk space usage of e-mail account was still wrong in cPanel.

To overcome the above issue one may need to login to ssh and fire the below mentioned commands:

1) Login as the root via ssh.

2) Delete the maildirsize file from the user account which is having the issue.

Location of the file is /home/domain/mail/domain.com/<e-mailaccount>/maildirsize

root@server1 [~]#rm /home/domain/mail/domain.com/<e-mailaccount>/maildirsize

3) Try to re-login to the cPanel. The file maildirsize will be automatically recreated.

After performing the above steps if the account still shows the wrong disk space usage, then proceed with the steps 4

4)Try deleting the following files:-

/home/domain/.cpanel/email_accounts.cache
/home/domain/.cpanel/email_accounts.yaml

Try to access the cPanel after few minutes which resolves the issue.
