sSMTP Debian Setup

The sendmail package, which comes preinstalled with many distros, is often simply too much for a simple server that should not receive emails but rather deliver them. The sSMTP package is a lightweight replacement that does not set up regular cronjobs and only reacts if a subsystem actually wants to send a mail.

Uninstall Sendmail

apt-get purge --yes sendmail*
