I am attempting to build a client that uses the javax.mail API to read email messages, including attachments. My initial thought was to use the Tika library. When that produced an unexpected result (please refer to code and details below), I tried using a variation of the code presented in this question.

My function for reading emails:

 // Reference: https://www.tutorialspoint.com/javamail_api/javamail_api_checking_emails.htm
public class CheckingMails {

 public static void check(String host, String storeType, String user, String password) 
 try 

 // create properties field
 Properties properties = new Properties();

 properties.put("mail.pop3.host", host);
 properties.put("mail.pop3.port", "110");
 Session emailSession = Session.getInstance(properties);
 Store store = emailSession.getStore("pop3");
 store.connect(host, user, password);
 Folder emailFolder = store.getFolder("INBOX");
 emailFolder.open(Folder.READ_WRITE);

 // retrieve the messages from the folder in an array and print it
 Message messages = emailFolder.getMessages();

 System.out.println("messages.length---" + messages.length);

 for (int i = 0, n = messages.length; i < n; i++) 
 Message message = messages[i];

 Object content = message.getContent();
 if (content instanceof java.lang.String) 
 System.out.println((String) content);
 else if (content instanceof Multipart) 
 Multipart mp = (Multipart) content;

 for (int j = 0; j < mp.getCount(); j++) disposition.equals(Part.INLINE))) 
 // Check if plain
 MimeBodyPart mbp = (MimeBodyPart) part;
 if (mbp.isMimeType("text/plain")) 
 System.out.println("Mime type is plain");
 System.out.println((String) mbp.getContent());
 else 
 System.out.println("Save file " + part.getFileName());

 
 
 
 

 System.out.println("Tika results " + parseMsg(message));

 

 // close the store and folder objects
 emailFolder.close(false);
 store.close();

 catch (MessagingException e) 
 e.printStackTrace();
 catch (Exception e) 
 e.printStackTrace();
 
 

When I test the program by sending a test message with a simple CSV as an attachment, the Tika parser outputs the following (truncated for brevity):

 ------=_NextPart_000_0028_01D47C16.81FB45C0
 Content-Type: application/ms-tnef;
 name="winmail.dat"
 Content-Transfer-Encoding: base64
 Content-Disposition: attachment;
 filename="winmail.dat"

------=_NextPart_000_0028_01D47C16.81FB45C0--

The other portion of the code (that checks for the message's disposition), outputs something similar to the following:

 messages.length---1
Mime type is plain



Email Boday



Save file winmail.dat

Why is the application reading/recognizing winmail.dat and not the attachment that was actually sent with the message (a CSV file)?

Thanks for any help.
