Message-ID: <20191025022800.GA29369@dcvr> MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Disposition: inline List-Id: Given my recent traumatic experience[*] around multiple From/To/Cc/Subject headers; I guess we should prepare for the possibility of multiple List-ID headers showing up in -mda. Right now, we handle the first one (and I'm updating -learn to support List-ID, too); but it's possible that multiple List-ID header can map to different inboxes, too...
