Good point py9jmas. Here is the full quote... 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.
How many out there are using a case sensitive email address system? Do you think there are some usability issues with case sensitivity?
