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 to AUTHENTICATE.
This way the client does not need to authenticate itself anymore.
This example trusts the
Mailserver (
MTA) and does not verify the TLS
certificate,
this is a workaround for missing root certificates seen often in private environments.
- Add and configure the following to /etc/s-nail.rc
set v15-compat
set smtp=<mailserver.com:587>
set user=<username>
set password=<password>
ssl-method=auto
set smtp-use-starttls
set ssl-verify=ignore
set smtp-auth=plain
Test
echo "TestText" | s-nail -s "TestSubject" user.name@domain.com
Keywords: mta mail tls ssl smtp pop pop3 imap message
