As I noted, the "mailto" is crontab specific (see: man -s5 crontab),
so where you need to change that value depends on the crontab the job
is invoked from. I believe that the /etc/crontab file is mostly
obsolete at this point, so I don't think changing the "mailto" there
has any real effect (except for jobs specifically put in there).

Note, some (generally) cron-invoked programs, e.g., logwatch, have
their own "mailto" settings, which will get used rather than what is
set in the crontab. You'll need to make script-specific adjustments
for these.

[please don't top post. turning off disclaimers that have no
relevance on list postings is also nice.]
