[SAC] mailman currently misbehaving

Hi community,
(cc OSGeo-SAC)

for currently unknown reasons many email addresses got blocked in
OSGeo's mailman server (mass "bouncing email addresses"). I have
opened a SAC ticket for that:

https://trac.osgeo.org/osgeo/ticket/2152

and hope that the admin in charge will pick it up asap.

sorry for the mess,
Markus
