The sender domain has a DMARC Reject/Quarantine policy which disallows sending mailing list messages using the original "From" header.
To mitigate this problem, the original message has been wrapped automatically by the mailing list software.
--- Begin Message ---Investigating why a device has rebooted can be difficult, especially if there's no output (for example during a kernel crash) on the serial console. Some watchdog drivers can tell us if the watchdog has caused the system to reboot. The corresponding WDIOF_CARDRESET flag is documented as: "Card previously reset the CPU". Add an info message if the watchdog supports the WDIOF_CARDRESET flag and if the boot status indicates that the watchdog has previously reset the system.
