Apple mail upload to yahoo hogging bandwidth

A frustrating issue!

It's possible that Apple Mail's upload to Yahoo is consuming excessive bandwidth, causing slow performance or even slowing down your entire network. Here are some potential solutions to help you troubleshoot and resolve the issue:

  1. Check your Yahoo account settings:
    • Ensure that your Yahoo account is set up correctly in Apple Mail. Go to Mail > Preferences > Accounts > [Your Yahoo Account], and verify that the account is configured correctly.
    • Check if there are any issues with your Yahoo account, such as a full inbox or a large number of unread messages.
  2. Adjust your upload settings:
    • Go to Mail > Preferences > Accounts > [Your Yahoo Account] > Advanced > Upload Settings.
    • Try reducing the upload speed or setting it to "Low" to see if it improves performance.
  3. Disable large attachments:
    • Go to Mail > Preferences > Accounts > [Your Yahoo Account] > Advanced > Attachments.
    • Set the maximum attachment size to a lower value (e.g., 1 MB) to prevent large files from consuming excessive bandwidth.
  4. Use a third-party email client:
    • Consider using a third-party email client like Microsoft Outlook or Mozilla Thunderbird, which may have better performance and bandwidth management.
  5. Check for malware or viruses:
    • Run a virus scan on your Mac to ensure that it's free from malware or viruses that could be causing the issue.
  6. Reset Apple Mail:
    • Go to Mail > Preferences > Accounts > [Your Yahoo Account] > Advanced > Reset.
    • This will reset the account settings to their default values.
  7. Contact Yahoo support:
    • Reach out to Yahoo's customer support to see if there are any issues on their end that could be causing the problem.
  8. Monitor your network usage:
    • Use tools like the Network Utility app (built-in on Macs) or third-party apps like Little Snitch or GlassWire to monitor your network usage and identify which applications are consuming the most bandwidth.
  9. Consider upgrading your internet plan:
    • If you're consistently experiencing slow speeds or bandwidth issues, it may be worth considering upgrading your internet plan to a faster speed tier.

By trying these steps, you should be able to identify and resolve the issue causing Apple Mail to hog your bandwidth when uploading to Yahoo.
