        Hi David,
        I don't think ISA is the problem here.
        The error message indicates that the message may not be relayed through 
        SMTP server.  Check the SMTP properties in Exchange.  Most likely need 
        configure to allow mail for your domain to be relayed through. SMTP
        properties can be found using Exchange System Manager --> SERVERS | 
        name> | Protocols | SMTP.
        Good luck..
