To determine if your email account uses POP3, take the following steps:
1. Open the email client that you use to access your email account. This could be Microsoft Outlook, Apple Mail, Gmail, Yahoo Mail, or another third-party email client.
2. Go to the email account settings or account details section of your email client. This will likely be found under the “Preferences” or “Settings” menus.
3. Look for the incoming mail server settings. This information will typically include the server name, port number, and authentication method.
4. Check the incoming mail server type. If it is listed as POP3, then your email account uses POP3. If it is listed as IMAP or Exchange, then it does not use POP3.
