When a queue file is initially created its permissions are 0600, with
the "execute" bit set (and fsync() called) once the message is fully
received, in SMTP just before returning a "250" response to the remote
client accepting resposibility to deliver the message.
So queue files with mode 0600 are typically in-progress or aborted
deliveries, with the latter for some reason not deleted when the
delivery was aborted. So if the files weren't incorrectly copied
into the queue, they're the result of aborted deliveries, perhaps
across a system crash that prevented just-in-time deletion.
What happened back in 2017, will remain a mystery unless you've retained
logs (or backups of same) from 2017.
