203376 - "virtual" subfolders for imap accounts

Status: RESOLVED DUPLICATE of bug 11051

(SeaMonkey :: MailNews: Message Display, enhancement)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4b) Gecko/20030411

All eMail providers I've tried so far (except fastmail) do not allow subfolders.

Would it be possible to display a folder as a subfolder even if the mailserver
doesn't know of this?

Example:
Folder 1 named ROOT
Folder 2 named ROOT.SUB

FastMail for example uses "." as separator this would be
|ROOT
|-SUB

On my primary account this the result is
|ROOT
|ROOT.SUB

I don't know how dificult it would be and if there is more functionality behind.

Anyway it would be nice to have an option to set a separator character (per
server) which would let mozilla parse the folder names and display a new
hierarchy level for every separator.

As far as I see it the file structure on the server wouldn't be different on a
server that does support subfolders and one that does not.
The difference is just the folders being reported as subfolders or not.

Reproducible: Always

I'm assuming you mean they don't allow subfolders of the account; even the 
restrictive provider I use allows subfolders of the Inbox.

However, virtual folders (not specific to IMAP) are unimplemented, and an old 
request.
