/bin/sh: 1: mail: not found

Recently I installed a VPS with web server, mail server, SSH server, typical. After establishing different crontab, in the first mail that I received this string appeared:

/bin/sh: 1: mail: not found

Related to a crontab line for root:

/root/scripts/copias.sh | mail -s "Informe copia joseblanco.pro" jblanco <em>at</em> joseblanco.pro

The solution was very simple:

aptitude install mailutils

See you!
