The main issue seems to be to limit access for notifications for
resources owned by a particular user or group. For CUPS, the
default configuration will allow only admin users to add notifications
for printer objects and job objects not belonging to a user. The
admin will be able to setup a server that allows greater access,
e.g. to monitor another user's jobs, but that won't be the default.
As for spam issues, there really isn't much we can do aside from
using HTTP authentication and/or limiting access to "trusted"
addresses to reduce the risk. Even if the spec didn't say the
address portion is opaque, what kind of filtering could actually
be done to provide effective spam protection? Sure, you could
prevent emails to specific domains, but that doesn't prevent DoS
attacks to local domains.
