Fwd: Non-standard IMAP flags in KMail

Subject: [Kolab-devel] Non-standard IMAP flags in KMail
Date: Monday 10 September 2007
From: Volker Krause <volkerkdab.net>
To: kolab-develkolab.org

Hi,

we have been implemeting support for storing all message
status flags of KMail 
on a Kolab server. So far only standard IMAP flags (seen,
answered, 
important) haven been stored there. For the non-standard
flags (todo, 
forwarded, ignored, watched) I have been looking at what
IMAP flags other 
mail clients use for that, with the following results:

- Outlook 2007 is claimed to support only one flag for IMAP
items, no idea if 
this is correct (I don't have it here to test it myself),
but it would mean 
there is no support for custom IMAP flags. Can anyone
confirm this?
- Thunderbird uses $labelN
- there is a draft dealing with extended IMAP flags: 
http://tools.ietf.org/html/draft-melnikov-imap-keyword
s-03
However, this still does not cover all flags we need
(watched and ignored are 
missing).

Has anyone additional information on that topic, ie. which
mail client uses 
what additional IMAP flags?

Overall, it seems that $<name> is the
"standard" way of dealing with extended 
flags that have a general, not client-specific meaning. So,
unless that 
conflicts badly with any other client out there, I would
suggest to follow 
that for KMail by using $ToDo, $Forwarded, $Ignored,
$Watched.

regards
Volker

Hi Volker,

can you please explain which new commands (if possible
verbatim) there will be 
on the IMAP tcp connection?

With which servers did you test?

Hi Volker,

I further investigated this matter.

It looks like you took a totally expired draft (anyone can
make up a draft) as 
a guideline.

I am afraid that this draft did not only expire but it also
did not get enough 
support fromt he community in order to become a RFC.

Did I overlook some aspect?

P.S.: - OL2K7 uses more than a single IMAP Flag
      - KONSEC Konnektor for OL would be able to use any
available IMAP Flag
        just as kmail.
      - For many purposes a plain boolean flag is not
enough. E.g. flags have
        colours and replied has a date....

I had hoped you would investigate the extended freebusy

Got anything better?
We tried to find what is there and how others solve the
problem.
This is the right approach. When there is just a
"totally expired draft",
I think it is better to work from there and develop a better
one, if we must
and can.

Got pointers?
Was it because of nobody was interested or there were
technical things
with it or other issues?

What does it use? Could you find out anything specific?

Any client would, if they implement the meaning...

I think we will see how far we get with the easier ones
first.
We can only put limited efforts in, 
so we should go for the lower hanging fruits first.

None, I guess. Would we need new commands?

Wouldn't this be more a client then a server issue?
