30000 email per day from a new ip address

A interesting scenario!

Receiving 30,000 emails per day from a new IP address can be a significant volume of email traffic. Here are some potential concerns and questions that come to mind:

  1. Spam or legitimate emails?: Is this a legitimate email campaign or a spamming activity? If it's the latter, it could be a sign of a malicious actor trying to exploit your email infrastructure.
  2. IP address reputation: Since it's a new IP address, it's likely that the IP's reputation is unknown or unverified. This could impact the deliverability of emails sent from this IP address.
  3. Email server capacity: Your email server may not be equipped to handle such a large volume of emails, which could lead to performance issues, delays, or even crashes.
  4. Email authentication: Are you using email authentication protocols like SPF, DKIM, and DMARC to verify the authenticity of emails sent from this IP address?
  5. Blacklisting: The IP address may be blacklisted by email providers or spam filters, which could prevent emails from being delivered to recipients.
  6. Compliance and regulatory issues: Depending on the nature of the emails, there may be compliance and regulatory issues to consider, such as GDPR, CAN-SPAM, or anti-spam laws.

To address these concerns, I recommend the following:

  1. Verify the IP address: Check the IP address's reputation using online tools like IPVoid, Spamhaus, or Barracuda's IP Reputation Tool.
  2. Monitor email traffic: Keep a close eye on email traffic from this IP address to detect any suspicious patterns or anomalies.
  3. Implement email authentication: Ensure you're using email authentication protocols to verify the authenticity of emails sent from this IP address.
  4. Configure your email server: Make sure your email server is configured to handle high volumes of email traffic and is optimized for performance.
  5. Contact the sender: Reach out to the sender (if you can identify them) to ask about the purpose of the email campaign and to verify their legitimacy.
  6. Report suspicious activity: If you suspect spamming or malicious activity, report it to the relevant authorities, such as your email provider's abuse department or law enforcement agencies.

Remember to stay vigilant and monitor your email traffic closely to ensure the security and integrity of your email infrastructure.
