E-mail usage is showing incorrectly in cPanel.

Sometimes you may face the issue with cPanel Disk space calculation between total disk space used and total E-mail folder size. For Example, the entire cPanel account showing you 100 MB while one of the Email accounts is showing the 350MB large size which is surprising.

Method 1: Please run the below command using SSH.


# /scripts/generate_maildirsize --confirm --allaccounts --verbose $USER

Note: replace the $USER with your actual cPanel user.

Method 2: Regenerate the maildirsize file for a specific email account:

  • Access the server via SSH.
  • Navigate to the mail directory: cd /home/username/mail
  • Remove the existing maildirsize file: rm -f maildirsize
  • Regenerate the file: /usr/local/cpanel/scripts/generate_maildirsize --confirm --email info@yourdomain.com
  • Replace info@yourdomain.com with the actual email address for which you want to regenerate the maildirsize file.


If the issue persists, log out the cPanel account and delete the email_accounts.yaml and email_accounts.cache files from the cPanel account's .cpanel directory. These files will be created automatically while you log in to the cPanel again.
