Mailman and DKIM

I have made Mailman work mostly with DKIM (and therefore DMARC). The
one remaining trick is this: Mailman will "simplify" mail addresses in
Cc (and maybe From and To) headers in some circumstances - which breaks
So, for an email address like:
Name <address at example.com>
if the "Name" is missing, Mailman will remove the "<" and ">". To get
around this, you can either always put a "Name", or lease out both the
"Name" and the "<>".
Sorry for the pain, hopefully most people can fix this in their address
And to be clear, this only matters where the originating site uses
DMARC with a strict policy (which includes samba.org).
