Remarks

The MailMessageEventHandler delegate modifies the contents of an Internet email message before the message is sent to the recipients. For example, you can add additional recipients or a custom message footer identifying your Web site to all messages using this handler.

The e parameter is a MailMessageEventArgs instance that contains the email message specified in the Message property.

When you create a MailMessageEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Handling and Raising Events.
