What's the best corporate email security policy for erroneous emails?

The issue here is that Uber doesn't verify email addresses, and these erroneous emails were being sent directly to a different user who was able to view private information on the real customer.

With that being said, if there are multiple emails incoming to an organization regarding accidental sign-ups or verification, it is an enterprise's right to block these incoming messages without question.

Unlike personal email, which the user has control over, corporate email security is the responsibility of the enterprise for which the employee works. This account, the emails and everything associated with it, are property of said organization.

If there is ever an issue with emails accidently being sent to the company and affecting it adversely, the company has the right to block these emails in its mail gateways or spam and phishing filters as part of the corporate email security policy. Read the rest of my article at the link below:
