97924 - Creating IMAP folders containing dot (.) makes a hierachy

Status: NEW

(MailNews Core :: Networking: IMAP, defect)

Description

[D Holroyd]

I select 'New Subfolder...' from the context menu and enter the folder name
'a.b'. Rather than seeing a new folder called 'a.b' as expected, I see a folder
called 'a' which further contains a folder called 'b' (also, the title 'a' is
italic grey, whatever that means?).

The IMAP server is Cyrus IMAP4 v2.0.11.  I've seen the problem on Win and Linux.

Confirming 20001083106 linux.

IMAP uses '.' to seperate foldernames.

The a is italic grey because it does not exist on the server, only INBOX.a.b exists.

Question is: Does IMAP support folder names with '.' ?

Answer is: YES. But Cyrus doesn't.
For example, Mozilla can create 'a.b' IMAP folder on CommunigatePro server without any problem.

Resume: This is Cyrus's only problem.
IMHO, this bug should be marked as INVALID.

Quote from RFC1730 (IMAP4 protocol):
-----
The interpretation of mailbox names is implementation-dependent.
...
If it is desired to export hierarchical mailbox names, mailbox names must be left-to-right hierarchical using a single character to separate levels of hierarchy
-----
But "single character" not defined. I.e. this is not Cyrus's problem, not Mozilla's problem. It is protocol problem :) For example, the same problem with CommunigatePro and '/' symbol.

The separator character is dependant on the server.  Shouldn't this bug be
marked invalid?

Maybe this bug should be an RFE to not allow creation of folders containing tyhe
servers path separator.
