When managing your website and email through cPanel, accurate storage data is essential. You rely on those statistics to maintain performance, keep within quota limits, and ensure proper functioning of your mailboxes. But what if e-mail usage is showing incorrectly in cPanel? You might be seeing 0 MB of usage when your inbox is full, or worse—cPanel is reporting high usage even after deleting hundreds of emails.
This issue is more common than you might think, and it often leads to confusion, panic, and support tickets. Whether you’re running a business-critical inbox or handling multiple email accounts on a shared hosting plan, it’s important to understand why these discrepancies occur—and how to fix or prevent them in the future.
The Importance of Accurate Email Usage in cPanel
Email storage usage in cPanel is shown under the Email Accounts section, where you can view how much space each email ID consumes relative to its allocated quota. This is vital for keeping your hosting account within limits and avoiding issues like:
- Bounced emails due to full inboxes
- Missing messages
- Hosting plan overages
- Inability to create new emails due to space limits
Why E-mail Usage is Showing Incorrectly in cPanel May Be Inaccurate
There are several reasons why E-mail Usage is Showing Incorrectly in cPanel, and most of them are not actually bugs—but rather, results of delayed updates or how cPanel calculates usage.
- Email Disk Usage is Not Recalculated in Real-Time
cPanel calculates usage periodically, not instantly. So when you delete emails, especially via webmail or an email client, the updated usage might not reflect right away. This is one of the most common causes of “phantom storage.” - Trash and Junk Folders Still Contain Data
Deleting an email doesn’t always remove it permanently. Often, messages go to the Trash or Junk folder. These folders still count toward the total usage unless you empty them. - Hidden or Cached Files
Some email clients (especially those using IMAP) store temporary or cached files within the account directory. These files aren’t visible via webmail but are still counted in usage stats. - Index Files and Metadata
cPanel stores index files to help webmail interfaces like Roundcube or Horde load faster. Over time, these can grow in size and inflate the reported usage. - Delayed Tallying by Dovecot
cPanel uses Dovecot as its mail server, and Dovecot runs a background service to calculate disk usage. If the service hasn’t run or is delayed due to server load, the numbers can appear outdated or inaccurate.
When and How Does cPanel Update Email Usage?
cPanel uses internal cron jobs (scheduled tasks) to scan directories and update usage data. These jobs typically run every 4 hours, but this may vary depending on the host’s configuration. In shared hosting environments, disk usage stats may refresh less frequently to reduce server strain.
If you’ve recently deleted a large volume of emails and the usage hasn’t changed, it’s likely just a matter of waiting for the next usage scan.
However, some hosts—including Hostrago—offer a “Recalculate Email Usage” option or can do so manually upon request via support. This triggers an immediate rescan of email data and updates your cPanel stats accordingly.
What You Can Do If the Email Usage Is Still Wrong
Here are some steps to help ensure email usage is displayed accurately:
- Manually empty Trash and Spam folders from webmail
- Use “Email Disk Usage” tool in cPanel to identify large folders and clear them
- Log out and log back in to refresh the view
- Contact your host to recalculate quotas manually
- In case of a stuck usage update, your hosting provider can reset Dovecot indexes to force accurate recalculation
