Email addresses are case sensitive. "mike at example.com" and
"Mike at example.com" are different email addresses. It just so happens
that most implementations treat them the same. There's no reason why
that has to be the case though.

The specification allows all sorts of insane local parts in email
addresses. Some good examples:

!#$%&'*+-/=?^_`{}|~@example.org
"()<>[]:,;@\\\"!#$%&'*+-/=?^_`{}| ~  ? ^_`{}|~.a"@example.org
