Re: [Qemu-discuss] ANNOUNCE: emails from this mailing list will soon drop the [qemu-*] subject tag

[Narcis Garcia]

Is far better mail servers use SPF and not DKIM.
DKIM is a signature between servers, but valid author's signatures are
far better done with PGP by author itself because is made by author and
verified by reader.

DKIM doesn't protect mail content autenticity at all, beginning with the
content sent from MUA to MTA.

PGP signatures are compatible with mailing lists footers and prefixes.
DKIM has only sense to mail servers control mail contents, and being
from same mail servers that contents can be hacked.
