Java EE (Java Enterprise Edition) General Discussion

Hi,

I'm using Javamail API 1.4.2 to read emails using IMAPS and POP3S. It looks like Javamail API adding some properties by default.Though I'm using the IMAPS to get mail store it's adding some plain imap related properties like mail.imap.fetchsize, mail.imap.statuscachetimeout, mail.imap.appendbuffersize and mail.imap.minidletime+.
see the debug trace below:

I have tried Jamail API 1.4.3 but the result is same. I think the protocols for IMAPS should be *mail.imaps.fetchsize, mail.imaps.statuscachetimeout,
mail.imaps.appendbuffersize* and mail.imaps.minidletime+.

Here is the code I have used to get the store
public static Store getMailStore(String protocol, String emailServerHostName,
int portNumber, String userName, String password) throws MessagingException {
Store store;
Properties props = new Properties();
boolean isSessionDebugEnabled = false;

props.put("mail.host", emailServerHostName);
props.put("mail.port", portNumber);
props.put("mail.user", userName);


props.put("mail.store.protocol", protocol);

Session session = Session.getDefaultInstance(props, null);
session.setDebug(true);
store.connect(emailServerHostName, portNumber, userName, password);
return store;
}



public static void main(String[] args) {
Store store = null;
try {
store = getMailStore("imaps", "myhost", 993, "myuser", "password");
Folder inboxFolder = openFolderForRW(store, "INBOX");
} catch (MessagingException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
}
}

Am I need to add these properties manually for IMAPS?

Thanks,
PrasadKT
