    Hi,

    I'm using exchange server and i can see in logs their are emails which are sending out from somedomain to someotherdomain which i really dont know about. But when I do some test on open relays, it says 'unable to relay' Here are some tcp stream which I captured of an email session.

    Code:
    220 mail.[COLOR="SeaGreen"][B]mydomain[/B][/COLOR].co.uk Microsoft ESMTP MAIL Service, Version: 6.0.3790.3959 
    ready at  Mon, 6 Jul 2009 15:14:18 +0100
