[hackerspaces] DMARC setting from yahoo disrupting mailing lists

[Georges Kesseler]

Hi

my mails from yahoo do not work anymore with mailman if it has not a
special setting
http://forums.cpanel.net/f43/yahoos-new-dmarc-policy-causing-mailman-bounces-402751.html
and this will completely change the behaviour of the mailing list. The
from headers will then all be "from <discuss at lists.hackerspaces.org>"
and if it works correctly they will be "from Givenname Surname via
<discuss at lists.hackerspaces.org>"
As this list has not yet this format, is there another way to work
around it or will this mail not reach half of the list (i.e. all gmail
users)

Anyone else has had problems with yahoo (or gmail) using mailman lists?
