Receipt Email for one Support Box but not the other

Content

Hello,

I have two Support Mailboxes set up within OSC. I need to have one send a Receipt email automatically on creation of a new incident, but not for the other box. I've been trying to work within Rules but have not been successful so far. (EX: If Incident.Incoming Mailbox equals [email protected], Then do not send Email Receipt Message. Else, Send Email Response to Sender)

What am I missing here?

Thanks,

Paul
