How to setup the server admin email address destination ?

I just installed a new server that does not send any login notifications as usual.
I was wondering where the administrator email address was configured or how it was guessed by the system, but did not find it.

Thanks for help


Those may be going to the “root” account… you can check /etc/aliases to see where those are going, or to change the current setting.


How stupid! Postfix was not running…
