Let's define the problem:
We are in an Microsoft exchange environment.
I have a mail box (MB1) that has to be monitored and every message has to be automaticly acknowledged by a message send back to the sender.
That box is attached to the another main account (MB2). It seems that I cannot define a specific rule for what is a secondary box (MB1) account.
I want to know if it is possible to define a rule specific to the secondary box (MB1).
