S-nail is an easy way to send email on Linux. The setup is quickly done and works with gmail, yahoo and others.
The following is an example setup which was tested on Ubuntu 20 and Debian 10/Buster

Installation

apt-get install s-nail

Configuration

This configuration is a quick sample of howto to use TLS with STARTTLS and PLAIN which suits for almost all mail server. It already contains the USERNAME and PASSWORD.
This way the client does not need to authenticate anymore. This example trusts the MTA and does not verify the TLS certificate, this is a workaround for missing root certificate seen often in private environments.

  • Add the following to /etc/s-nail.rc
set v15-compat 
ssl-method=auto
set smtp=<your-mailserver.com>
set user=<username>
set password=<password>
set smtp-use-starttls
set ssl-verify=ignore
set smtp-auth=plain

Test

echo "TestText" | s-nail -s "TestSubject" user.name@domain.com
