Description Martin Bednar 2016-11-29 23:23:41 UTC
Reply to mailing list produces a reply with an empty "TO" header, which it then (correctly) refuses to send.

From what I see, the list adds the following mailing-list related headers : 
List-ID: <netfilter.vger.kernel.org>
X-Mailing-List: netfilter@vger.kernel.org

In the kmail GUI, the header shows the list Id.

From what I understand, kmail uses the "reply-to" header to recognize the mailing list. Could it also use List-ID if it contains a valid email? (no idea how workable that is...)
If not, then at least notifying about missing information (why the "TO" field is empty) would be nice.

Could you attach mail as mbox for testing ?

Not sure if it is the mbox format, it is what I found in my .maildir folder (maintained by dovecot). Hope it helps.

We can't use list-id as default reply to list element.
But we define it in kmail folder properties
