Is it possible (maybe through database) to duplicate the spamassasin preferences (Learn Ham/Spam) from one user to another?
Take a look at the sa-learn command. For example
Thanks for your quick reply, I already did this for several users now. Is it also possible to take (for instance) my spamsettings and apply them serverwide? and do users still have the ability to learn spam/ham then?
Considering the effectiveness of this functionality we are thinking of providing all our customers with a baseline set of spam rules.
You can set this in NodeWorx for either per user or server wide.
