Email Accounts Showing Incorrect Disk Usage After Deleting Emails

Symptoms

After removing emails from the email accounts, the disk usage for the email accounts in the Email Accounts section in cPanel is not updated or accurate. 

Cause

The email address shows incorrect disk space usage due to the maildirsize file for the email accounts not being updated. The maildirsize file does not always update live, depending on the action(s) taken.

Resolution

Note: "CPUSER" in the following examples must be replaced with the cPanel username of the account in question.

1. Log in to the server via SSH or WHM's Terminal as the root user

2. Move the maildirsize files out of the way with the following command:

   # find /home/CPUSER/mail/ -type f -name maildirsize | while read line; do mv -v $line{,.$(date +%s)}; done

3. Regenerate the cPanel user's maildirsize files:

   # /usr/local/cpanel/scripts/generate_maildirsize --confirm CPUSER

4. Move the cPanel user's email_accounts.json file aside:

   # mv -v /home/CPUSER/.cpanel/email_accounts.json{,.$(date +%s)}
