A bit old, but still really useful, i used this method on a server. Article by Tom, first posted on Tombuntu
Wouldn’t it be useful if your computer could email you? I’d like to be notified by email when my server is in trouble, but I don’t want to run my own mail server. sSMTP is perfect for this; it’s a simple way to send email from your system to an SMTP mail server, like Gmail’s.
Here’s how I set up sSMTP on Ubuntu to send mail through my Gmail account.
Install sSMTP from the package ssmtp (click the link to install on Debian/Ubuntu), or by running the command below in your terminal:
sudo apt-get install ssmtp
sSMTP can be configured from one text file. Open /etc/ssmtp/ssmtp.conf in a text editor:
sudo gedit /etc/ssmtp/ssmtp.conf
The configuration file is very short and well commented by default. Here’s the options I use for sending mail through Gmail:
AuthMethod=LOGIN # This is needed only for Gmail
If you’re using Gmail like I am, change the root, authuser, and authpass options to the email address, username, and password of your Google account. If you’re using another mail service you’ll need to change mailhub to the relevant SMTP server.
Once your configuration work is done, time to try sending some mail! The simplest way to do this is to run sSMTP in a terminal with a recipient email address:
ssmtp [email protected]
Note the blank like after the subject, everything after this line is the body of the email. When you’re finished, press Ctrl-D. sSMTP may take a few seconds to send the message before closing.
Now it’s easy to write scripts which can send you mail. Here’s an example terminal command to send an email from the msg.txt text file:
ssmtp [email protected] < msg.txt
