The University of Toronto Capture the Flag (uoftctf.org) is a prominent organization in the computer and network security industry, with a strong presence in Toronto, Ontario, Canada. As a leading entity in the cybersecurity space, it's essential for uoftctf.org to maintain a robust email infrastructure. However, verifying emails from this domain can be a significant challenge, especially when it comes to catchall emails.

Challenges of Verifying Emails at uoftctf.org

Verifying emails at uoftctf.org can be problematic due to several reasons:

• Email Security Gateways (ESG): uoftctf.org may employ Email Security Gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.
• Catchall Emails: uoftctf.org is set to catchall, which means that traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify emails accurately.
• No Bounce Messages: uoftctf.org may not always return a bounce message even if you send test messages to an invalid email address at that domain, making services like Scrubby ineffective.

Risks of Not Verifying Emails at uoftctf.org

Not verifying emails at uoftctf.org can lead to several risks, including:

• Risky Emails: Other services may leave most emails at uoftctf.org as risky, leaving you uncertain about how to handle them. If you keep the emails, you may risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
• Outdated Lists: If you don't verify emails, your list will become outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
