You can save your emails with POP3 in the following ways:
1. Set up a local email client such as Outlook, Thunderbird, or Apple Mail and download all your email messages to your computer. This way, you can access your emails even when you’re offline.
1. Export your emails from your email client to a PST, MBOX, or EML file. This will create a backup of your emails that you can store on your computer or an external hard drive.
1. Forward your emails to another email address or save them as a PDF file. This is a good option if you only want to save specific emails and not your entire mailbox.
Keep in mind that when you use POP3, emails are stored on your local device, so it’s important to regularly back up your emails to ensure you don’t lose them in case of a computer failure, theft or other event.
