Since revision
731356a155
and the fact `mail.mass_mailing.campaign` inherits (with s)
from `utm.source`, and the name of the mass mailing
is took from this `utm.source` linked to the mass mailing,
a mass mailing user requires the write access on the model `utm.source`
to be able to change the subject of a mass mailing.
As a side node, I notice there is no group applied on the
base `access_utm_source` access rule of the module UTM,
meaning a portal user can create `utm.source`.
I am not sure if this is wanted or not.
