231095 - IMAP default folders are case sensitive; creates undesired duplicate folders

Status: RESOLVED EXPIRED

(Thunderbird :: Mail Window Front End, defect)

Description

[mozilla]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/85 (KHTML, like Gecko) Safari/85
Build Identifier: Mozilla Thunderbird 0.5a (20040105)

Mozilla by default creates IMAP folders such as Inbox, Sent, and Trash. While
Inbox seems to be case insensitive (i.e. a second instance called Inbox is not
created when INBOX exists), Sent and Trash (and probably Drafts) are case
sensitive. To illustrate, if there sent and trash folders already on the server
(i.e. using SquirrelMail web interface), Mozilla will nevertheless create Sent
and Trash folders, resulting in Sent, sent, Trash, and trash.

There appears to be no way to override this behavior.

I believe this is the same in MailNews.

I'm not sure if this really qualifies for a bug. Reading from the IMAP RFC
(http://www.isi.edu/in-notes/rfc3501.txt):

   The case-insensitive mailbox name INBOX is a special name reserved to
   mean "the primary mailbox for this user on this server".  The
   interpretation of all other names is implementation-dependent.

   In particular, this specification takes no position on case
   sensitivity in non-INBOX mailbox names.  Some server implementations
   are fully case-sensitive; others preserve case of a newly-created
   name but otherwise are case-insensitive; and yet others coerce names
   to a particular case.  Client implementations MUST interact with any
   of these.  If a server implementation interprets non-INBOX mailbox
   names as case-insensitive, it MUST treat names using the
   international naming convention specially as described in section
   5.1.3.

Even if Thunderbird initially creates those folders, you can always change them
in the Account Settings dialog to whatever folder you want and then delete the
new ones that Thunderbird created.

I recommend marking as INVALID, but will wait for the reporter to respond.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
