I kind of like seeing the qemu-devel prefix, since I don't tend to
pre-filter email into separate folders per list. I only do per-list
filtering (on headers) once at start of the day when reading the
overnight backlog. For rest of the day have a single inbox and tend
to rely on subject alone.

Of course the prefix isn't entirely reliable regardless, as if you
are CC'd on mails you'll probably see the copy delivered via the CC
long before you get the copy via the list.

AFAIK, the libvirt mailing list isn't mangling From lines, and it
also has a subject prefix added, so I wonder why it doesn't have
a need for the same workaround wrt DMARC ?  Or maybe it does need
it and we've never realized.

Daniel
