I think this email is missing a References: header ?
It doesn't get threaded properly.

Yes, that was indeed a bug that has now been fixed, thanks for
reaching out!

Thank you!

One more thing, would it be possible to add / correct the DKIM on these
messages? Looks like when our bots load the syzbot ci emails from lore
the DKIM verification fails. I see a X-Google-DKIM-Signature: header,
but no real DKIM-Signature:

Thanks for letting us know!
Do these bots also face DKIM verification issues with regular syzbot
emails? We send them absolutely the same way, so the problem must
affect all reports.

We use the GAE Mail API, and its documentation[1] says that it signs
emails with DKIM only if a custom domain is configured. Since we send
from the default GAE domain, this would explain the verification
failures.

We'll explore the ways to fix this.
