I am using a network-less LXC container with a small debian stretch setup, which contains exim4 and probably, nothing more from mail related programs.
I am able to send mails to the root user and I can see them in /var/mail with name mail (>/var/mail/mail) with owner and group set to mail and only this user has r/w access I can cat them, naturally). I want to be able to quickly type >mail and read them. This is just a control function. I really do not want to create extra users (on soo many containers), maintain their password, change aliases, login and read the mail of root.
After nearly a whole day of searching, I am unable to understand where to read more about it or why this propblem occurs.
This is really very annoying. Could someone probably explain?
Thanks anyway!
