The local mailbox portion (bit before the "@") of email addresses is case sensitive.
In practice, most email providers don't actually honor that, and so in practice it's a bad move. It is technically correct though.

I guess I never thought to look that up. Likely due to the common way being so pervasive.

We lower-case all e-mails in our systems. I'll let you know when we hit a system that actually treats it case-sensitive.
"the local-part MUST be interpreted and assigned semantics only by the host specified in the domain part of the address."
