I suspect strongly that it has a lot to do with the sender’s use case. Marketing email is very often customized to the recipient (adding their name perhaps, or changing the identifiers on embedded links) so those are single recipient. But mailing lists might be a very different story. This week’s delays on IETF mailing lists make me wonder if that might have been significantly worse if they had to be sent (and signed) individually to each recipient. -Jim _______________________________________________ Ietf-dkim mailing list -- ietf-dkim@ietf.org To unsubscribe send an email to ietf-dkim-le...@ietf.org
