Re: [Classpathx-discuss] Which application uses GNU JavaMail ?

[Cedric Hyppolite]

Hi Chris,

I used tcpflow with Gnu provider. Sun did take into account the  
mail.debug property so I got the command directly.

Sun provider does:
A6 LIST "" "INBOX/%"
* LIST () "/" INBOX/sent-mail
* LIST () "/" INBOX/JXTA
* LIST () "/" INBOX/Pouic
* LIST () "/" INBOX/spam
* LIST () "/" INBOX/NonSpam
* LIST () "/" INBOX/Apple
A6 OK LIST completed

where Gnu provider does:
A10 LIST INBOX %
* LIST () "/" INBOX
A10 OK LIST completed

- Another difference is that Sun provider gives the folder a type 3  
(holds folder & messages) where Gnu provider gives a type 2 (holds  
message).

- Sun provider throws a FolderNotFoundException on listing of the  
personal/user/shared namespace, where Gnu gives an empty array. I  
prefers the GNU provider behaviour.

- On the logging problem: I am running under Eclipse, but that should  
not prevent logging from working as I use commons-logging and log4j  
without problems.

Conclusion:
On the folder type issue, I guess everything (but the root) should be  
of type 3 even if there is no 'inferior' folder for now i.e. the API  
says for HOLDS_FOLDER: 'This folder CAN contain other folders'.

It may happen that both list commands are valid but one is 'more  
supported' that the other.
I let you make the fix on your side. I guess it is pretty obvious now.

Regards,
Cedric
