Do you know of any servers that are case sensitive?

Postfix. In the local user case. Alias and Virtual are not but local accounts are (because username is case sensitive)

It depends on configuration. I doubt very many SMTP servers are case sensitive in this day and age. This is not the case on my Postfix servers. Sendmail was also case insensitive in its default configuration (though it has been many years.)
