I have a colleague who uses Exchange 2003 and collects all of the incoming and outgoing email for archive purposes. It is all dumped into an Email Archive account. Is there a way to create a server side rule which will delete email which is only sent internally.
To clarify, if the message goes from email@example.com to any other addresses @abc.com, then it should be deleted. If the message goes to an address at abc.com, but is to or cc'd or bcc'd to any other domain, then it should not be deleted.
