Exchange 2010 sending spam email
Posted on 2013-06-28
I have an exchange 2010 server which is passing spam email through to my barracuda SPAM firewall which has the emails stuck in an outbound queue. The emails are being sent from a non-existent user spoofing our domain which is apparently passing through exchange 2010. Is there a way to track this back to the originating IP address of the infected workstation? I've tried using message tracking in Exchange 2010, but that seems to be useless.
