Challenges of Verifying Emails from ydu.edu.tw

Verifying emails from ydu.edu.tw can be challenging due to several reasons:

  • Email Security Gateways (ESGs): It's unclear whether ydu.edu.tw uses ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
  • Catchall Emails: ydu.edu.tw is set to catchall, which means simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter cannot verify these emails.
  • No Bounce Messages: ydu.edu.tw may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby ineffective.

Risks of Not Verifying Emails from ydu.edu.tw

Not verifying emails from ydu.edu.tw can lead to:
