We use SBS2003 with Exchange 2003 and use an SMTP Connector with a smart host because we are are on a dynamic IP address. The smart host is a static IP and we're refrened it by name but some of our messages are being marked as SPAM because it is picking up that the messages were orginally sent from a dynamic IP address. SPAM Assasin flags it up as being a dynamic IP on teh SORBS list etc...
Have I configured something wrong in the connector or will the orginating IP always appear in the message header??
