Bart

Security

bart uses the net/smtp package, which uses TLS if possible. Still, just to be safe, I explicitly discourage using bart for mission-critical information.

Installation

From source

$ make install

Binaries

You can get them from GitHub releases.

Usage example

You want to send an HTML email stored as a Mustache template in template.mustache. Your configuration (see below) is defined in config.bart.yml.

To preview the rendered emails, call bart without the send -s flag:

$ bart -t template.mustache -c config.bart.yml
Hello, Jane Doe
Send flag not set: opening preview in "chromium-browser"
Send flag not set: opening preview in "chromium-browser"

To send the email, add the send flag -s:

$ bart -t template.mustache -c config.bart.yml -s
Hello, Jane Doe
Please enter your credentials for "smtpserver.xyz.com"
Login: janedoe
Password:
Will send to [john.doe@abc.com jane.doe@xyz.com]
Will send to [max.mustermann@def.de jane.doe@xyz.com]

Since this email will not appear in your provider's Sent folder, bart will send you a BCC copy.

For help, call bart -h.

How to configure

Here's an example config file:

author:
  name: Jane Doe
  email: jane.doe@xyz.com
  browser: chromium-browser

email_server:
    hostname: smtpserver.xyz.com
    port: 123

global_context:
  subject: Global subject

recipients:
  john.doe@abc.com:
    salutation: Hi John
    subject: Local subject, overrides global one
  max.mustermann@def.de:
    salutation: Hello Max

Basically, recipients is a hashmap keyed by recipient email addresses; the values are local contexts specific for each recipient. Notice that local context overrides global one!
