I'm trying to use GreenMail as a mockup mail server for unit testing. It's job is to await a IMAP/POP3 request and deliver a dummy mail, but I can't get it to work.
public class EMailMonitoringTest {
private static final String USER_PASSWORD = "test";
private static final String USER_NAME = "jDownloaderTestUser";
private static final String EMAIL_USER_ADDRESS = "jdtest@localhost";
private static final String EMAIL_TO = "someone@localhost.com";
private static final String EMAIL_SUBJECT = "Test E-Mail";
private static final String EMAIL_TEXT = "This is a test e-mail.";
private static final String LOCALHOST = "127.0.0.1";
private GreenMail mailServer;
@Before
public void setUp() {
mailServer = new GreenMail(ServerSetupTest.ALL);
mailServer.start();
}
@After
public void tearDown() {
mailServer.stop();
}
@Test
public void getMails() throws AddressException, MessagingException, FolderException, UserException, IOException {
// create user on mail server
GreenMailUser user = mailServer.setUser(EMAIL_USER_ADDRESS, USER_NAME, USER_PASSWORD);
// create an e-mail message using javax.mail ..
MimeMessage message = new MimeMessage((Session) null);
message.setFrom(new InternetAddress(EMAIL_TO));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(EMAIL_USER_ADDRESS));
message.setSubject(EMAIL_SUBJECT);
message.setText(EMAIL_TEXT);
// use greenmail to store the message
user.deliver(message);
// check received messages
Message[] messages = mailServer.getReceivedMessages();
for (Message m : messages) {
System.out.println("*** Class: " + m.getClass() + " ***");
System.out.println("From: " + m.getFrom()[0]);
System.out.println("To: " + m.getRecipients(Message.RecipientType.TO)[0]);
System.out.println("Subject: " + m.getSubject());
System.out.println("Content: " + m.getContent());
}
No problem here, the output so far is what it look like:
** Class: class javax.mail.internet.MimeMessage **
From: someone@localhost.com
To: jdtest@localhost
Subject: Test E-Mail
Content: This is a test e-mail.
After that, I try to get the mail from the GreenMail IMAP server:
// fetch the e-mail via imap using javax.mail ..
Properties props = new Properties();
Session session = Session.getInstance(props);
URLName urlName = new URLName("imap", LOCALHOST,
ServerSetupTest.IMAP.getPort(), null, user.getLogin(),
user.getPassword());
Store store = session.getStore(urlName);
store.connect();
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
messages = folder.getMessages();
System.out.println("Size of Messages: " + messages.length);
for (Message m : messages) {
System.out.println("** Class: " + m.getClass() + " **");
System.out.println("From: " + m.getFrom()[0].toString());
System.out.println("To: " + m.getRecipients(Message.RecipientType.TO)[0].toString());
System.out.println("Subject: " + m.getSubject().toString());
System.out.println("Content: " + m.getContent().toString());
}
and my reward for this is a
Size of Messages: 1
** Class: class com.sun.mail.imap.IMAPMessage **
and a FolderClosedException:

Trying to access folder.getMessage(0) just results in a IndexOutOfBoundsException, but there IS one Message of class IMAPMessage stored in the Array. Someone knows about this?
Ah yes, I tried the examples on hashCode, but they also fail with the same reason... FolderClosedException when accessing the properties of the received IMAP message...
Gratefully would accept any hints.
