I need curstom RoutingAgent class and send Moderate Message. how to do is . thanks all.
use ILSpy tool see ModerateMessageByUserAction source code :
namespace Microsoft.Exchange.MessagingPolicies.Rules.Tasks
[Serializable]
public class ModerateMessageByUserAction : TransportRuleAction
private const string InternalActionName = "ModerateMessageByUser";
private const string AddressDelimiter = ";";
private SmtpAddress[] addresses;
[LocDescription(Strings.IDs.ToAddressesDescription), LocDisplayName(Strings.IDs.ToAddressesDisplayName), ActionParameterName("ModerateMessageByUser")]
public virtual SmtpAddress[] Addresses
get
return this.addresses;
set
this.addresses = value;
internal override string Description
get
string text = RuleDescription.BuildDescriptionStringFromStringArray(Utils.BuildSmtpAddressStringList(this.Addresses), Strings.RuleDescriptionAndDelimiter);
return Strings.RuleDescriptionModerateMessageByUser(text);
protected override void ValidateRead(List<ValidationError> errors)
if (this.Addresses == null || this.Addresses.Length == 0)
errors.Add(new RulePhrase.RulePhraseValidationError(Strings.ArgumentNotSet, base.Name));
return;
SmtpAddress[] array = this.Addresses;
for (int i = 0; i < array.Length; i++)
SmtpAddress smtpAddress = array[i];
if (!smtpAddress.IsValidAddress)
errors.Add(new RulePhrase.RulePhraseValidationError(Strings.InvalidRecipient, base.Name));
return;
base.ValidateRead(errors);
internal static TransportRuleAction CreateFromInternalAction(Action action)
if (action.get_Name() != "ModerateMessageByUser")
return null;
List<SmtpAddress> list = new List<SmtpAddress>();
string stringValue = TransportRuleAction.GetStringValue(action.get_Arguments().get_Item(0));
string[] array = stringValue.Split(new string[]
}, StringSplitOptions.RemoveEmptyEntries);
string[] array2 = array;
for (int i = 0; i < array2.Length; i++)
string text = array2[i];
SmtpAddress item = new SmtpAddress(text.Trim());
list.Add(item);
if (list.Count == 0)
return null;
return new ModerateMessageByUserAction
Addresses = list.ToArray()
internal override Action ToInternalAction()
StringBuilder stringBuilder = new StringBuilder();
SmtpAddress[] array = this.Addresses;
for (int i = 0; i < array.Length; i++)
SmtpAddress smtpAddress = array[i];
if (!smtpAddress.IsValidAddress)
throw new ArgumentException(Strings.InvalidRecipient, "Addresses");
string value = smtpAddress.ToString();
if (string.IsNullOrEmpty(value))
throw new ArgumentException(Strings.InvalidRecipient, "Addresses");
if (stringBuilder.Length > 0)
stringBuilder.Append(";");
stringBuilder.Append(value);
ShortList<Argument> shortList = new ShortList<Argument>();
shortList.Add(new Value(stringBuilder.ToString()));
return TransportRuleParser.Instance.CreateAction("ModerateMessageByUser", shortList);
Anything is Possible！

Hi, Glen.<o:p></o:p>
Thanks your reply. Your solution is of great help to me.<o:p></o:p>
I can add a keywords in x-header as transport rule predicate,
but the transport rule action how to do dynamic sets a approval user.<o:p></o:p>
Because I extended Outlook client and user selection who approved.<o:p></o:p>
What's the good suggestions and ideas?<o:p></o:p>
Thanks.<o:p></o:p>
