@Sandeep

That’s because you’re not supposed to edit /etc/sudoers. You’re a human. That file is not for humans. Do not attempt to edit that file. Instead, run the command visudo.

Vivek: I have the same problem as Rolf. My sudo version is 1.6.9p17

And this is what happens:
I am editing /etc/sudoers with visudo. The result of adding 3 lines which you can find below:

Defaults env_reset
mailto “admin@staff.example.com”
mail_always on

is that I’m getting error message:

ambrozy@zeus:~$ sudo visudo
>>> sudoers file: syntax error, line 8 <<>> sudoers file: syntax error, line 10 <<<

with "Defaults" at the beggining it's working fine:

Defaults !lecture,tty_tickets,!fqdn,!syslog
Defaults logfile=/var/log/sudo.log
Defaults mailto="noc@wired.pl",mail_always
Defaults mail_badpass, mailsub="** BAD AUTHENICATION: %U %h **"
Defaults mail_no_user, mailsub="** USER NOT IN SUDOERS: %U %h **"
Defaults mail_no_perms, mailsub="** SUDO PERMISSION ABUSE: %U %h **"

I want to configure SUDO password when I use sudo command in terminal than It should be ask for password every time.
When I use putty and cert key than it is not asked for password.

@Rolf,

Can you tell us about your sudo version?

By: Rolf

I had to write it like this:
Defaults mailto="sudoers@domain.com",mail_always

Thanks! This is one more step in creating a secure server environment and it keeps me from having to check the log files often.
