  "message": "Add b4.custom-msgid-cmd for replies and notifications\n\nReview replies and thank-you notes are sent directly over SMTP via\nsend_mail(), bypassing git-send-email and therefore any\nsendemail-validate hook that would normally rewrite the Message-Id.\nThese messages thus always got a built-in \u003c...@b4\u003e id, with no way for\nmaintainers who rely on their own message-id scheme to override it.\n\nAdd an opt-in b4.custom-msgid-cmd option: when set, run it and use its\nstdout as the Message-Id (angle brackets optional), falling back to the\nbuilt-in id when unset, empty, or on failure. Rather than introduce a\nparallel make_msgid() variant, fold the hook directly into make_msgid()\nbehind an allow_custom_msgid_cmd flag and flip it on at exactly the\nreply/notification call sites: review replies, follow-up replies, and\nb4 ty thank-you notes.\n\nSeries patches sent with b4 prep/send are unaffected, since they derive\ntheir message-ids from make_msgid_tpt() rather than make_msgid(). The\nsynthetic b4 pr GIT PULL messages are likewise left alone, as their ids\nare deliberately derived from the pull request and anchored to\ngithub.com.\n\nKey changes:\n- make_msgid() grows an allow_custom_msgid_cmd flag that consults the\n  new b4.custom-msgid-cmd config when set\n- Enable the flag for review replies, follow-up replies, and ty notes\n- Document b4.custom-msgid-cmd in docs/config.rst\n- Add unit tests covering opt-in, bracket handling, list-valued config,\n  and fallback on unset/failing/empty-output commands\n\nSuggested-by: Christian Brauner (Amutable) \u003cbrauner@kernel.org\u003e\nLink: https://lore.kernel.org/r/20260522-review-msgid-cmd-v1-1-facc71f2e084@kernel.org\nAssisted-by: claude-opus-4-8\nSigned-off-by: Konstantin Ryabitsev \u003ckonstantin@linuxfoundation.org\u003e\n",
