Btw, these four patches alone are pushed to http://git.infradead.org/users/dwmw2/edk2.git/shortlog/refs/heads/csm-ovmfp= kg But... this cover letter has been detached from the thread with the patches= . When git-send-email created them, the cover letter had Message-Id: <20190626113742.819933-1-dwmw2@infradead.org> All the subsequent patches had: References: <20190626113742.819933-1-dwmw2@infradead.org> But they all get their message-id corrupted on the way through the list, it seems. So the References: headers in the patches are referencing a Message-ID: that no longer exists.=20 Why does the list do this? Can it be turned off, please? Or at the very least, can it be set to mangle References: and In-Reply- To: headers to match the corruption it introduces into the Message-Id: headers and at least keep threading intact? That still doesn't keep things in sync with messages that *don't* go through the list though, so fixing it not to do any corruption at all would be best. --=-9U38Qq7N+lEo1RCVmgQf Content-Type:
