Ubuntu Send Mail From Command Line

Mail is part of the mailx i.e mailutils on Ubuntu so we will install this first.

Note: mailutils will also spawn the postfix installation. instead of having postfix ask us a lot of questions during install we will install postfix interactively 

DEBIAN_FRONTEND=noninteractive apt install -y postfix
apt install mailutils
