</span>Probably not yet, if you're just looking at North America. A number of<br>
mailbox providers of one type or another around the world have done<br>
similar things in the past two years - Mail.ru, LaPoste.net in France -<br>
and some in the US (GMail) have said they'll follow suit... soon.<br>
<br>
I expect "soon" to be defined when the ARC protocol<br>
(<a href="http://arc-spec.org" rel="noreferrer" target="_blank">http://arc-spec.org</a>) or something similar has implementations available<br>
in the field. It's very close, but it isn't quite there yet.<br>
<br>
In the meantime the Mailman list manager offers several workarounds for<br>
these situations in version 2.1.19 and later, but people are<br>
understandably irritated when those options mean changing the behavior<br>
of an existing list. Others take umbrage at the workarounds themselves.<br>
(Example: changing the address portion of the From: header to be the<br>
list address instead of the original author.)<br>
<br>
Configuring a list so that it doesn't make changes that break DKIM<br>
signatures from the original author's domain would obviate the need for<br>
all this, but people like their subject tags and footers...<br>
