Thanks for looking into this, David!

But I don't see kernelci.orgbot referenced anywhere in the emails.
E.g. in the one that was linked above:
https://groups.google.com/forum/message/raw?msg=syzkaller-bugs/OkwLGoS6UQA/hHAtCdnNBgAJ

Which one do you mean? syzbot takes emails from get_maintainers.pl, I
guess kernelci.orgbot is not usually there. And syzbot does not
includes names, just email addresses.
Could a dot in email address produce the same result? E.g.
To: foo.bar@xxxxxxxxxxxxx
? I see such addresses in some of the emails (but not in the one
referenced above).

Is it possible to revive autoanswer@xxxxxxxxxxxxxxx? It would
hopefully allow us to debug this without bothering you.


Possibly related, when I am searching for "syzkaller" I am finding
entries like the following titled "This message generated a parse
failure. Raw output follows here. Please use 'back' to navigate.".

https://lkml.org/lkml/2018/3/10/73
https://lkml.org/lkml/2018/2/27/581
https://lkml.org/lkml/2018/2/22/774

Could this "parse failure" explain the undelivered emails? How can I
figure out what exactly caused the failure?

Thanks again
