This still seems to happen on bugs.debian.org mails, for example I got RUF reports like:
Authentication-Results: mail.susi-moog.de; dkim=fail reason="signature verification failed" (1024-bit key; unprotected) header.d=voyager.hr header.i=@voyager.hr header.b=jhX0w52b; dkim-atps=neutral It is really problematic, because if person reporting bug uses DKIM, and MTA of package maintainer (or other subscribed persons) verifies it, then the bug report might never reach the maintainer / interested subscribers. This is especially likely to happen if DMARC is also used with policy different than "none". Could some solution/workaround (like #500965 for similar problems in lists.debian.org) be adopted? -- Opinions above are GNU-copylefted.
