Question - Are e-mail addresses case sensitive?
Answer -
If you're uncertain if an e-mail address is case sensitive it's safe to assume it's not.Typically most Internet Service Providers (ISPs) and e-mail servers are not case sensitive. which means INFO@exammaterial.com is the same as info@exammaterial.com. However, the first portion of an e-mail address (alias/username/group) can be case sensitive. This means if the server is case sensitive logins INFO, info, and Info would all be considered different users and each of those users would have different e-mail addresses.
