When there is no "date" field, it is displayed as unknown. It happens every days with spams. But a fallback date could be found in the "received" field. Related detail: the mails without date appears at the bottom of the list and it is boring to view/remove them. A light fix could be to display them before the most recent ones. Reproducible: Always

There's something similar though not exactly the same here. I am receiving emails from the servers of National Internal Revenue Service of Bulgaria, which have the date field, and the "received" field but the date is still displayed as unknown. In some of the emails the date field is like this: Date: Tue, 9 Apr 2013 14:16:45 +0300 and the date of the email in Kmail is displayed properly, But in other emails the date field is like: Date: Fri, 12 Apr 2013 16:48:45 +03:00 and the date of the email in Kmail is displayed as "Unknown".
Created attachment 80458 [details] email shown with date "Unknown"
it's a kdelibs bug Date: Fri, 12 Apr 2013 16:48:45 +03:00 it doesn't work because it wants : Date: Fri, 12 Apr 2013 16:48:45 +0300 => without ":"
Yes, I guess this is the reason. My system is Slackware14.0 and KDE 4.10.4. Thunderbird & Seamonkey Mail parse this date anyway and don't show "Unknown date" notice. I would like Kmail to be able to parse this as well. I am aware that this is perhaps not standard compliant, but since such a situation (syntax) can happen in the wild (in my case this is the mail server of the tax administration) then there must be a way to parse this string in such a way as to extract the correct date of the message . Even more so , because Kmail has been and still is my main email client. Regards, Todor
Another clue as to why it happens! There's a text in the problematic email that reads: X-Library: Oracle utl_smtp I hope this helps. Apparently this office uses an Oracle application to send email.
