It should not be allowed to create uppercase alias addresses ( yes user
dont care ever about lower and upper case )
this leads to problems at modoboa install
with wanted postfix matches like

reject: RCPT from
host....: 550 5.1.1
T1@example.com: Recipient address rejected: User unknown;
from=someone@example.com to=T1@example.com
proto=ESMTP helo=<[10.1.2.3]>
