Apple mail client for yahoo is downloading all emails

It sounds like you're experiencing an issue with the Apple Mail client for Yahoo where it's downloading all emails instead of just the new ones. This can be frustrating and wasteful, especially if you have a large email inbox.

Here are a few potential solutions to help you resolve this issue:

  1. Check your Yahoo account settings: Make sure that your Yahoo account is set to only download new emails. You can do this by logging into your Yahoo account on a web browser, clicking on the gear icon, and selecting "Settings." Then, click on "More Settings" and look for the "Account" or "Mail" settings. Make sure that the "Download new emails" option is set to "Only new emails" or "New emails only."
  2. Update your Apple Mail client: Ensure that your Apple Mail client is up to date. You can do this by opening the App Store, searching for "Apple Mail," and clicking on the "Update" button if an update is available.
  3. Disable the "Download all emails" option: In Apple Mail, go to "Mail" > "Preferences" > "Accounts," select your Yahoo account, and click on the "Advanced" tab. Look for the "Download" section and uncheck the box next to "Download all emails." This should prevent Apple Mail from downloading all emails.
  4. Use IMAP instead of POP: If you're using POP (Post Office Protocol) to connect to your Yahoo account, try switching to IMAP (Internet Message Access Protocol). IMAP allows you to access your emails on the server without downloading them to your local machine. To switch to IMAP, go to "Mail" > "Preferences" > "Accounts," select your Yahoo account, and click on the "Account" tab. Look for the "Account type" dropdown menu and select "IMAP."
  5. Reset your Apple Mail client: If none of the above solutions work, you can try resetting your Apple Mail client. To do this, go to "Mail" > "Preferences" > "Accounts," select your Yahoo account, and click on the "Reset" button. This will reset your Apple Mail client to its default settings.
  6. Contact Yahoo support: If none of the above solutions work, you may want to contact Yahoo support to see if there are any issues with your account that could be causing the problem.

I hope one of these solutions helps you resolve the issue with your Apple Mail client downloading all emails from your Yahoo account.
