I'm building an application that will periodically process a batch of 
requests sent in by e-mail (before you ask, there are good reasons why it 
won't be run continuously). The code is running well in testing using Ben 
Fortuna's MSTOR extension to read test e-mails from a set of files: in 
production it will be using POP3 to read from a mail folder.

I've just started POP3 testing and have run into a problem. It is 
successfully opening the mailbox it is configured to treat as input and 
connection to the default folder, INBOX, but is then failing to open that 
folder in READ_WRITE mode - I'm using mode that so I can delete each 
request message after processing it. However, initial tests are all 
failing to open the INBOX, which is empty. It just throws a 
MessagingException containing the message "Open failed". 

So, my question, should javax.mail.Folder.open() open an empty folder 
successfully or not? The documentation gives no clue about it.
