Description kolAflash 2016-02-08 15:44:52 UTC
KMail version 4.14.9

When forwarding a message, KMail doesn't set the "In-Reply-To" and the "References" headers.

Could anyone check this for the current KMail version? (4.15.x)

One workaround would be, to specify custom headers in the forward template. But this would require this bug to be solved first.

Then you could do something like:
References: %OHEADER="References" %OHEADER="Message-ID"
In-Reply-To: %OHEADER="Message-ID"

Reproducible: Always

Looks like Thunderbird is also setting this reasonable additional header when forwarding.
X-Forwarded-Message-Id: ...

So a header-template could look like this:
References: %OHEADER="References" %OHEADER="Message-ID"
In-Reply-To: %OHEADER="Message-ID"
X-Forwarded-Message-Id: %OHEADER="Message-ID"

I don't know if the original reporter of this bug is still around, but I can confirm the issue is still present in KMail 5.21.3.

None of the References:, In-Reply-To: or X-Forwarded-Message-Id: headers are set when forwarding a message.
It makes no difference if the message is forwarded inline or as an attachment.
