            Bug ID: 15296
           Summary: The Busybox sendmail command does not add a Message-ID
           Product: Busybox
           Version: 1.35.x
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: Other
          Assignee: unassigned at busybox.net
          Reporter: sven.kirmess at kzone.ch
                CC: busybox-cvs at busybox.net
  Target Milestone: ---

The following command run on illumos with the real sendmail gets sendmail to
add a Message-Id header.

    echo "To: me at example.net\nSubject: test" | sendmail -ti

If I run this command (on Alpine Linux) with the Busybox sendmail it does not
add a Message-Id header.
(BusyBox v1.35.0 (2022-11-19 10:13:10 UTC) multi-call binary.)

    echo -e "To: me at example.net\nSubject: test"  | sendmail -ti

Unfortunately, gmail does reject mails without a Message-Id. And, although the
RFC violation seems to be with Google, I would suggest that the Message-Id
header is added as it would increase compatibility with real sendmail and serve
better for the intended purpose (sending mails as easy as possible).
