I have a server that hosts a java application that is allowed to send out emails. During testing I want postfix to send all outgoing email to test-javaapp@my-company.com, however email that sent to sysadmin@my-company.com needs to be left alone.
Basicly:
sysadmin@my-company.com --> sysadmin@my-company.com*@* --> test-javaapp@my-company.com
