John answers:

The local-part is case sensitive, therefore jsmith@example.com and JSmith@example.com specify different mailboxes. This practice is discouraged by RFC 5321, however. Most email servers ignore case. I would recommend sending email to yourself both ways to make sure your server accepts it. I have never heard of it being a problem with Yahoo.
