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.
From: Sergiy Kibrik <sakib@darkstar.site>

Otherwise modules with long names, e.g. lttng (>32 chars) can't be loaded.
