450 user is receiving mail too quickly tnmpmscs yahoo

It sounds like you're experiencing an issue with your Yahoo account where you're receiving emails too quickly from a specific user (450) using the TNMPMSCS email address.

To help you troubleshoot this issue, I have a few questions:

  1. Are you receiving multiple emails from this user in a short span of time, or is it a single email that's being delivered repeatedly?
  2. Have you checked your email filters or spam settings to see if there's a rule or setting that might be causing this issue?
  3. Have you tried marking the emails from this user as "not spam" or "not junk" to see if that helps resolve the issue?
  4. Are you experiencing any other issues with your Yahoo account, such as slow loading times or difficulty accessing your inbox?

Additionally, you can try the following steps to help resolve the issue:

  1. Log out of your Yahoo account and log back in to see if that resolves the issue.
  2. Check your email settings to ensure that you're not receiving duplicate emails from this user.
  3. Try deleting the emails from this user and see if that resolves the issue.
  4. If the issue persists, you can try contacting Yahoo's customer support team for further assistance.
