Introduction

SystemMail is a Ruby library built to compose and deliver internet mail using operating system utilities.

SystemMail features:

• tiny memory footprint even with big attachments
• blazing-fast gem loading and message composing
• alternating message body format: text, enriched, HTML
• rich capabilities in attaching files
• ability to combine HTML message with file attachments

Operating system commands used to do the job are:

• sendmail -t < temp or alternative sends the message to Mail Transfer Agent
• base64 file >> temp encodes binary files to textual form
• file --mime-type --mime-encoding -b file detects Content-Type and charset

Installation

Add this line to your application's Gemfile:

gem 'system_mail'

And then execute:

$ bundle

Or install it yourself as:

$ gem install system_mail

Usage

mail = SystemMail.new(
  from: 'user@example.com',
  to: ['user1@gmail.com', 'user2@gmail.com'],
  subject: 'test проверочный subject',
  files: ['Gemfile', 'Gemfile.lock'],
