    The following C#-code uses System.Management, System.DirectoryServices and
    System.Reflection

    DirectoryEntry SMTPServer = new
    DirectoryEntry("IIS://localhost/SMTPSVC/1");
    SMTPServer.RefreshCache();
    object oIPSecurity = SMTPServer.Invoke("Get", new string[]{"IPSecurity"});
    Type t = oIPSecurity.GetType();
    //Get the list of denied IPs
    Array IPs = (Array)t.InvokeMember("IPDeny",
    BindingFlags.GetProperty, null, oIPSecurity, null);
    //create a new Array of IPs
    object[] newIPs = new object[IPs.Length+1];
    //copy the existing IPs to the new Array
    IPs.CopyTo(newIPs,0);
    //add a new value
    newIPs.SetValue("192.168.0.21",IPs.Length);
    //Set the new IPlist
    t.InvokeMember("IPDeny",
    BindingFlags.SetProperty, null, oIPSecurity, new object[]{newIPs});
    SMTPServer.Invoke("Put", new object[]{"IPSecurity", oIPSecurity});
    SMTPServer.CommitChanges();
