Probably because the NetBSD list, unlike the tuhs list and most others,
doesn't mess with the headers or body in any way - not by attaching a
"helpful" tag to the Subject, and not by appending an xtra fake sig with
Either of these "modern" paractices will invalidate the source DKIM
signature, and so also trigger a DMARC reject if a strict policy is set.
By the way, my inbound processing automatically strips the Subject tag
before I get to see the messages. It is useless.
Please don't Cc: me privately on mailing lists and Usenet,
if you also post the followup to the list or newsgroup.
Do obvious transformation on domain to reply privately _only_ on Usenet.
