how do i change postfix case insensitive

Hi I’m using postfix 2.3.3 I have it all setup and working except that if I send and email to [email protected] postfix will report unknown user and bounce the message, but if I send it to [email protected] the message is sent. I need to be able to have case sensitive user names can any one help me change this please. Thank you, JOE

 

Hi!
If a change like this is possible it might lead to a lot of misstakes in sending mail.People might not remember the cases of e-mail addresses.
