I never really understood the organisation of mail for notifications in Unix, but I always took for granted that system notification mails was an inescapable fact.
However I just tried to start
idle3.8 with the
at now command (in order to avoid having it stuck in a terminal) and since it failed (it works in a terminal), I wanted to check the mail notifications
atd should have sent... and there was nothing.
Cannot open mailbox /var/mail/camion: Permission denied
No mail for camion
$ ls -l /var/mail/
Is this situation normal / due to a misunderstanding from my side, or is there some action I should undertake in order to solve this problem. I have seen some people suggesting to just create the missing file/folder with the correct permission, but this seem mostly cosmetic and doesn't explain why/how this problem arose.
