While the LHS of an email address is case-sensitive in the standard, most
mail systems do not treat it as case-sensitive without going to special
work to configure them to do so, which means that in practice relying on
that case-sensitivity is unlikely to work.  We should probably say that
explicitly, but I think the provision of the text here is correct.
