Challenges of Verifying Emails at wi.hs-osnabrueck.de
Verifying email addresses at wi.hs-osnabrueck.de can be challenging due to several reasons:
- Catchall Emails: wi.hs-osnabrueck.de is set up as a catchall domain, which means that it can be difficult to verify email addresses using traditional verification methods.

- Email Security Gateways (ESGs): wi.hs-osnabrueck.de may use ESGs, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make it difficult to verify email addresses using simple SMTP tests.
- Lack of Bounce Messages: wi.hs-osnabrueck.de may not always return a bounce message even if you send a test message to an invalid email address, making it difficult to verify email addresses using services like Scrubby.
