This behavior cannot be changed.
The host name part of the email address cannot be treated in a
case-sensitive fashion per RFC821 and pretty much any other standard that
mentions them. Here's a quote from section 2 ("THE SMTP MODEL") of RFC821:
| Commands and replies are not case sensitive. That is, a command or
| reply word may be upper case, lower case, or any mixture of upper and
| lower case. Note that this is not true of mailbox user names. For
| some hosts the user name is case sensitive, and SMTP implementations
| must take case to preserve the case of user names as they appear in
| mailbox arguments. Host names are not case sensitive.
