Using the JavaMail API with JDBC - Java Database Programming Bible - page 411

After connecting to the Store, get a folder and open it. Using POP3, the only folder available is the
INBOX . Once the folder is open, you can read messages from it, as shown here:
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
Message message[] = folder.getMessages();
The folder.getMessages() method uses lazy data retrieval . In other words, the message content is
only downloaded when specifically requested. You can get the content of a message with
getContent() or write the content to a stream with writeTo() . The getContent() method only
gets the message content, and writeTo() output includes headers. Here's an example:
System.out.println(((MimeMessage)message).getContent());
Notice that the INBOX is opened in READ_ONLY mode. Write access can be used to mark messages as
received or to delete them from the server. Listing 16-3 illustrates how easy it is to receive e-mail
messages using the JavaMail API.
