Verifying Catchall Emails at Vulnhub.com: How to Avoid Risks with BounceBan

As a sales and marketing professional, you understand the importance of maintaining a clean and accurate email list. However, verifying emails from certain domains can be a daunting task, especially when dealing with catchall emails. In this blog post, we'll explore the challenges of verifying emails at vulnhub.com and how BounceBan can help you overcome these challenges.

About Vulnhub.com

Vulnhub.com is a platform that provides a virtual environment for learning and practicing penetration testing and vulnerability exploitation. The domain is set up to receive emails from various sources, which can make verifying emails a complex task.

Challenges of Verifying Emails at Vulnhub.com

Verifying emails at vulnhub.com can be challenging due to several reasons:

  • Catchall Emails: Vulnhub.com is set up to catch all emails, which means that simple SMTP tests used by traditional verification services may not work. This is because catchall emails are not verifiable using traditional methods.
  • Email Security Gateways: It's unclear whether vulnhub.com uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos. If they do, it would make simple SMTP tests fail.
  • No Bounce Messages: Vulnhub.com may not always return a bounce message even if you send test messages to an invalid email address. This makes it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at Vulnhub.com

Not verifying emails at vulnhub.com can lead to several risks, including:

  • High Bounce Rates: If you don't verify emails, your list will be outdated, and you'll risk seeing a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate.
  • Risky Emails: Other services may leave most emails at vulnhub.com as risky, so you don't know how to deal with them. If you keep the emails, you may risk seeing a high bounce; if you delete all of them, you risk missing potentially valuable valid emails.
