Email disk space

To see the current disk usage for all your POP accounts, log in to the SmarterMail interface as the 'Postmaster' account.

To log in as Postmaster, go to the Email Management page in the Site Info Manager section of Control Panel.
Click the "SmarterMail Manager" text and you'll be taken to the SmarterMail interface. Once logged in to webmail, go to Reports > Domain Summary Reports > Traffic Reports > Disk Usage. There you can see all users, their disk usage, their inbox quota, and Totals / Disk Total.

Note:  SmarterMail doesn't query the physical disk, the Max Disk Total will show the sum of the users quotas. Therefore it's possible that Max Disk Total can show a limit greater than your actual disk limit. The "Total Disk" column under the "Disk Usage" report will show the true disk usage for each of your POP accounts.

If you've reached your Email Disk Space limit, you can upgrade your Winhost plan or remove emails to free disk space up. See this KB article to upgrade your Winhost plan. If you have deleted email, you may need to remove it from the recycle bin to free the disk space.
