215777 - Labels and mail status is cleared when moving mails between folders using IMAP.

Status: RESOLVED FIXED

(MailNews Core :: Networking: IMAP, defect)

Description

[Gabor Nagypal]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; rv:1.4) Gecko/20030624
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; rv:1.4) Gecko/20030624

We use an Exchange Server which I access with Mozilla using IMAP (secured SSL
accesss). When I move a mail between folders both labels (Later, Important etc.)
and mail status (Read, Forwarded, Reply etc.) are reset which is very annoying. 
Moreover, even spam status is cleared, i.e. all of my spam mails, which are
identified via Mozilla as such, and moved to my spam folder automatically loose
their spam mark.
With POP3 accounts labels, status and spam-status are not cleared.

Reproducible: Always

Steps to Reproduce:
1. Set a label on a mail, or reply to a mail, or set spam-status
2. Move the mail to another folder.


Actual Results:  
All of the meta-information is lost.

Expected Results:  
As in POP3 case, keep the metadata.

Tried with mozilla 1.5beta and also with non-exchange IMAP server (imap.web.de),
but still does not work. All of the additional info is lost when I move a mail
between IMAP folders. Perhaps it is a Win2k specific issue if it really works
for WinXP?

your imap server isn't supporting user-defined keywords, which is where we store
this information.

Is there a list of imap servers somewhere which are compatible with Mozilla Mail?
If my IMAP server does not support user-defined keywords, how do they stored
until I do not move mails between folders (those info remains there
persistently)? Where those keywords are stored then? In .msf files? Isn't it
possible to store them there even when you move mails between folders?

Does it mean that Mozilla will never work with MS Exchange Server (and other
server which are not "Mozilla-compatible"? The present situation (at moving all
of the info lost, even reply status and attachment info, which are quite
standard stuff) renders Mail almost unusable with those servers.

I believe this is a dup - it should be fixed now.

Comment 6

It still does not work for me (Mozilla 1.6 on Win 2000). I tried it with our
corporate exchange server, and with web.de IMAP (uses Linux as far as I am
concerned).
With POP3 accounts it works OK, but with IMAP accounts labels are lost. 
In the header of IMAP I do not see any X-Mozilla-Status tags, where label
information should be stored. (In POP3 mails I see the headers.)
Could someone give me the name a (possibly free) mail provider, where IMAP
access was succesfully tested with Mozilla? Then I could test it also to make
sure that it is an IMAP server problem.

IMAP doesn't use x-mozilla-status headers; we use imap keywords. If your server
doesn't support IMAP user-defined keywords, things get trickier but we do
attempt to handle it, at least locally to one machine (we can't handle it across
client machines, obviously, if the server doesn't support IMAP user-defined
keywords). I believe fastmail.fm does support user defined keywords but I'd have
to shut down to make sure.

-> all/all as i'm seeing this on Mac OS X.

is this a dupe of bug 189016?

ah, junk status is maintained, but labels are not. I need to extend the same
trick I did for junk status to labels, for those imap servers that don't support
user-defined keywords.

Comment 11

Attachment: fix for labels

this makes it so labels will be kept if you copy a message with a label set to
an imap server that doesn't support user defined keywords.

fixed

Okay, now it works to move labeled message *to* the IMAP server, but not *to*
local folders. Was that excluded on purpose?
