Challenges of Verifying Emails from tsu.edu.cn
Verifying emails from tsu.edu.cn can be challenging due to several reasons:
- Catchall Emails: tsu.edu.cn is set to catchall, which means that simple SMTP tests used by traditional verification services may not work. Catchall emails are emails that accept all incoming emails, regardless of the recipient's existence.
- Email Security Gateways (ESGs): tsu.edu.cn may use ESGs, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. These gateways can make simple SMTP tests fail, making it difficult to verify emails.
- No Bounce Messages: tsu.edu.cn may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby not work.
Risks of Not Verifying Emails from tsu.edu.cn
Not verifying emails from tsu.edu.cn can lead to several risks:
