📨 Send emails right from your terminal.
We use this tool to send an informational email whenever someone logs in to one of our servers. Intended usage is via pam_exec(8).
Emails are sent directly via SMTP. The config is read from a json file, see Config.
The message body is produced via go templates, see Templates.
Download an archive (.tar.gz) from the latest release and run the install.sh script.
Add the following snippet to /etc/pam.d/sshd:
session required pam_exec.so /usr/local/bin/smtp-cli -config /usr/local/etc/smtp-cli/config.json -template /usr/local/etc/smtp-cli/template.gotmpl
