Defines whether SOAP message security is enabled.

Namespace: Microsoft.ServiceModel.Channels.Mail
Assembly: Microsoft.ServiceModel.Channels.Mail (in Microsoft.ServiceModel.Channels.Mail.dll)

Syntax

'Declaration
Public Enumeration MailSecurityMode
'Usage
Dim instance As MailSecurityMode

public enum MailSecurityMode

public enum class MailSecurityMode

type MailSecurityMode

Members

	Member name	Description
	None	SOAP message security is disabled. This is the default value.
	Message	SOAP message security is enabled.

Remarks

By default, the mail binding sets SOAP message security to MailSecurityMode.None, which disables SOAP message security.

When SOAP message security is enabled, the mail binding uses an AsymmetricSecurityBindingElement. SOAP message security for the mail transport is based on X.509 certificates. The default values for AsymmetricSecurityBindingElement properties are as follows:

MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10
SecurityHeaderLayout = SecurityHeaderLayout.Lax
MessageProtectionOrder = MessageProtectionOrder.SignBeforeEncrypt
IncludeTimestamp = true
SecurityBindingElement.LocalServiceSettings.TimestampValidityDuration = 24 hours.
SecurityBindingElement.LocalClientSettings.TimestampValidityDuration = 24 hours.

For device-based applications, the following default settings are also used:

SecurityBindingElement.LocalClientSettings.DetectReplays = false
SecurityBindingElement.LocalServiceSettings.DetectReplays = false

For desktop applications, the following default settings are also used:

SecurityBindingElement.LocalClientSettings.ReplayWindow = 24 hours
SecurityBindingElement.LocalServiceSettings.ReplayWindow = 24 hours
System.ServiceModel.Channels.AsymmetricSecurityBindingElement.InitiatorTokenParameters.RequireDerivedKeys = false
System.ServiceModel.Channels.AsymmetricSecurityBindingElement.RecipientTokenParameters.RequireDerivedKeys = false

If you need to change the default SOAP message security, you can instantiate all binding elements and pass them to the constructor for a CustomBinding object instead of using a class that is derived from the MailBindingBase object. Alternatively, you can call the CreateBindingElements method to return the binding elements, change the value on specific binding elements, and then pass the binding elements to a CustomBinding object.

Examples

The following example shows how to enable message security for the mail binding. For the complete code example, see the MailSecurity class.

Dim binding As ExchangeWebServiceMailBinding
Dim clientEmailServer As New Uri("https://mail.example.com")
Dim clientEmailAddress As String = "client@example.com"
Dim password As String = "password"

binding = New ExchangeWebServiceMailBinding(clientEmailServer, New NetworkCredential(clientEmailAddress, password))
binding.Security.Mode = MailSecurityMode.Message

ExchangeWebServiceMailBinding binding;
Uri clientEmailServer = new Uri("https://mail.example.com");
string clientEmailAddress = "client@example.com";
string password = "password";

binding = new ExchangeWebServiceMailBinding(clientEmailServer,
                                           new NetworkCredential(clientEmailAddress, password));
binding.Security.Mode = MailSecurityMode.Message;
