Access & Read Embedded Email Attachments From Existing Email Message

				
//**************************************
// Name: Access & Read Embedded Email Attachments From Existing Email Message
// Description:This technical tip shows how to Read Embedded Email Attachments from Message. Sometimes, we get emails that have other emails embedded in them as an attachment. These embedded emails are complete messages having their own Recipients list, Subject, Body and Attachments. Furthermore, each of these messages can have embedded messages in them. Using Aspose.Email Java API, the developers can access each embedded message as an individual message. We will elaborate such example using recursive functionality.
