Bug in TIdIMAP4.ListMailBoxes()

[rlebeau]

When ListMailBoxes() is executed on a Lotus Notes server, lines are returned that may look like this:

* LIST (\HasNoChildren) "\\" Folder\Subfolder 1
* LIST (\HasNoChildren) "\\" Folder\Subfolder 2

In the resulting list this is stored as

[0] LIST
[1] \HasNoChildren
[2] \
[3] Folder\Subfolder
[4] 1

The IMAP server's response is valid according to the protocol.

There are two "failing" procedures: InternalParseListResult and ParseIntoBrackettedQuotedAndUnquotedParts.

Shouldn't ParseIntoBrackettedQuotedAndUnquotedParts simply regard everything after the delimiter as a Folder path?

InternalParseListResult doesn't check idx 2 as Delimiter, instead it takes the one to last entry and takes the first character of that. In the example, the delimiter would become 'F'. It also decides that the last index is the folder name, so the folder ends up as '1' or '2'. It should take the delimiter from LSlRetrieve[2] and regard LSlRetrieve[3] and higher as the folder name.

When ListMailBoxes() is executed on MS Outlook server, everything works as expected, as that returns lines like this:

* LIST (\HasNoChildren) "." "INBOX.Folder.Subfolder 1"
* LIST (\HasNoChildren) "." "INBOX.Folder.Subfolder 2"
