Differences between POP and IMAP
IMAP (Internet Message Access Protocol)
- The default way a mobile device accesses your Yahoo Mail account.
- Changes made to messages on a mobile device automatically reflect in Yahoo Mail on the web and vice versa.
POP (Post Office Protocol)
- Yahoo Mail messages are delivered directly to your email client.
- Copies of messages in both Yahoo Mail and the email client are independent of one another.
- Make changes to messages on your email client without impacting their counterparts in your web-based Yahoo Mail.
- You must configure your email client to keep a copy of your messages on our server or your emails will automatically be deleted from Yahoo Mail on the web.
- Check with the manufacturer of your mail client for assistance configuring this setting.
