unicorn:~$ apt-cache show ssmtp [...] Description-en: extremely simple MTA to get mail off the system to a mail hub A secure, effective and simple way of getting mail off a system to your mail hub. It contains no suid-binaries or other dangerous things - no mail spool to poke around in, and no daemons running in the background. Mail is simply forwarded to the configured mailhost. Extremely easy configuration. The entire point of this package is that it's meant to be used on a "dumb client" which does not wish to have its own outgoing mail queue. Instead, it forwards all of your mail to your "smart host" -- the MTA that has been set up for your organization's dumb clients to use. So, the single piece of information you need in order to use ssmtp is the hostname of your smart host. Also known as your mail relay. Or many other names. It's where you want your outgoing mail to be handled.
