we prefer s-nail over mailutils and bsd-mailx as it does NOT install exim4 as a dependency on debian systems.

    apt install s-nail
    ln -s s-nail /usr/bin/mail
    ln -s s-nail /usr/bin/mailx

    grep -vE '^#|^$' /etc/s-nail.rc

nmap -25 SMTP-RELAY

Acceptance

    # slackware
slackpkg install s-nail
    tail -F /var/log/secure /var/log/maillog

    # debian
apt install s-nail
ln -s s-nail /bin/mail
    tail -F /var/log/auth.log /var/log/mail.log

    hostname --long | mail -s test root
