If you want to free up space in a mailbox, whether for preventive maintenance or because the mailbox is full and new emails are not arriving, you must follow the steps in this manual.

  1. Freeing up space via Webmail

To free up space via Webmail, you must access the mailbox for which you want to perform the space clearance using a URL in your web browser. There are two ways to write the URL:

mail.domain/webmail

mail_server_name/webmail

Once the login page loads, you will have to enter the mailbox and the corresponding password to access it. For more information about Webmail access, you can consult the following manual: https://swpanel.com/ca/comunidad/manual/roundcube-webmail

Deleting emails in Webmail

In order to free up space, you must select and delete emails. We recommend selecting emails with attachments (which are "heavier" emails and take up more space) that are no longer needed. For the space clearance to be effective, once the emails are deleted, you must empty the “Trash” folder and, after doing so, you will have successfully freed up disk space.

If the mailbox is full and you try to delete emails, the following error may appear: “Server error: UID COPY: Quota exceeded (mailbox for user is full)”

If it appears, to be able to delete the email, you must do so using the key combination Shift + Del. With this key combination, the email will be deleted without passing through the Trash folder.

  1. Configure your email client (Outlook, Gmail, Thunderbird…) in POP3

The POP3 protocol is the protocol through which emails from the server are downloaded to your computer and then deleted from the server, automatically freeing up the space occupied by that email. Therefore, configuring your email client will prevent the disk space of your email server from collapsing. To do this, you will have to change the configuration of your email client:

You will need to find out which port the POP3 protocol uses on your server. You can do this by following the following manual:
