I have exchange 2010. I have open SMTP ( Port 25 ) for a another specific server which is running an application which sends emails within the organisation. This application is not compatible with SMTP authentication. Therefore I have assigned it to a open receive connector. I have allocated a specific email address for this application too instructing that emails from this host should be from this give email address only.

I want a way to block emails if this application tries to send emails from another email address other than the assigned email account.

Please advise me on this.

There is no way to achieve that unless you write a custom transport agent.
