I have developed mail client using JavaMail API. It shows only one folder that is Inbox while retreiving messages from POP3 Server.
I want to show all other folders like OUTBOX, Deleted Item, Sent Items and Trash also.
Please suggest me a solution for my problem.
Thanks in advance.
That's how POP3 behaves. If you need to see other folders on the server, you need to use the IMAP protocol. IMAP is included free with JavaMail, and is quite common on servers. If other mail software can see multiple folders, I would guess that IMAP is already running on that server, so just change your JavaMail config to use IMAP and have a go.
