Yahoo email blacklist

The infamous Yahoo email blacklist!

In 2013, Yahoo suffered a massive data breach, which led to the compromise of over 3 billion user accounts. As a result, many Yahoo email accounts were added to various blacklists, including those maintained by internet service providers (ISPs), email providers, and security companies.

Here are some of the most notable blacklists that Yahoo email addresses are often associated with:

  1. Spamhaus: Yahoo email addresses are listed on the Spamhaus Project's "PBL" (Policy-Based List) and "XBL" (Exploits Block List) due to the high volume of spam and phishing emails sent from compromised accounts.
  2. Sender Score: Yahoo email addresses have a poor reputation on the Sender Score, a scoring system used by Return Path to measure the quality of email senders. This can lead to deliverability issues and increased spam filtering.
  3. Comcast's Email Blacklist: Yahoo email addresses are blocked by Comcast's email system due to the high volume of spam and phishing emails sent from compromised accounts.
  4. AT&T's Email Blacklist: AT&T's email system also blocks Yahoo email addresses due to the same reasons as Comcast.
  5. Gmail's Spam Filter: Yahoo email addresses are often flagged as spam by Gmail's filters, which can lead to emails being sent to the spam folder or even blocked entirely.

To avoid being blacklisted, it's essential to maintain good email hygiene practices, such as:

  1. Keeping your account secure: Use strong passwords, enable two-factor authentication, and keep your account up to date.
  2. Monitoring your account activity: Regularly check your account activity to detect and report any suspicious behavior.
  3. Reporting spam and phishing emails: Report any spam or phishing emails you receive to Yahoo's abuse department.
  4. Using a reputable email client: Use a reputable email client or webmail service to send and receive emails.
  5. Avoiding spamming and phishing: Refrain from sending spam or phishing emails, as this can harm your reputation and lead to blacklisting.

By following these best practices, you can help maintain a good reputation for your Yahoo email address and reduce the risk of being blacklisted.
