testmail with specific date header

Version:           unspecified (using Devel) 
OS:                Linux

I noticed, that some mails are shown with a date "Unknown" in kmail2.

Looking deeper with akonadiconsole akonadi has no date in the Browser for such messages too.

Affected are at least all mails with the following "Date:" header format:

Date: Sat, 18 Dec 2010 14:01:21 "GMT"

Maybe the problem is the "GMT" or the quotes around it.
(X-mailer: AspMail 3.02 (QSMTEF5782))

mutt can handle that mail without any problems (as well as the webmail that I am using)



Reproducible: Always

Steps to Reproduce:
* Put a Mail with a Date: header like this into your mailbox:
  Date: Sat, 18 Dec 2010 14:01:21 "GMT"


Actual Results:  
* Read that mail kmail2 or akonadiconsole it will show "Unknown" in kmails message list and "Date:	Sun Feb  7 07:28:15 2106" in the mailview.


Expected Results:  
Date should be read correctly and displayed according to the local timezone

Sorry, mixed up bug numbers here.
Comment 3 Marc Schiffbauer 2012-03-19 21:15:08 UTC
This Bug is still present (akonadi 1.7.1 / KDE 4.8.1)
Comment 4 Marc Schiffbauer 2012-05-20 10:42:34 UTC
This bug is still present (4.8.3+ (current 4.8 git branch, akonadi 1.7.2)
Comment 5 Marc Schiffbauer 2012-05-20 10:48:42 UTC
Additional note: when kmail is configured to jump to the newest message when selecting a folder it will fail on folders which contain messages with dates that akonadi cannot handle properly and jump to some of those messages with an "Unknown" date instead (which are listed at the very end of the list).
Comment 6 Marc Schiffbauer 2012-05-24 09:07:19 UTC
Hi Volker,

I just had a look at RFC 5322. Having "GMT" as Timezone in the Date Header is supported but deprecated. However, those mails I am having Problems with seem to be created by some mail software where they misunderstood the RFC a little bit. ( http://tools.ietf.org/html/rfc5322#page-33 )

The RFC talks about "GMT" but the double uotes are not part of the real String that can be used. E.g. it should be written as GMT and not "GMT". So the example mail is indeed not 100% RFC compatible.

However: I really think this kind of header should nevertheless be parsed as expected because real world shows that there *are* mails like this in the peoples mailboxes. 

So please accept "<some RFC 5322 obs-zone>" (with double quotes) as well as without (which should already be the case) 

*And* mutt for example does not have a problem with those mails...

-Marc

Comment 10 Marc Schiffbauer 2012-07-15 00:57:20 UTC
Thanks for your patch, but this bug is not fixed by that
Comment 11 Denis Kurz 2016-09-24 20:56:20 UTC
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of kdepim (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.
Comment 12 Denis Kurz 2017-01-07 22:02:27 UTC
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
