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();
