MailsViewer

MailsViewer is a mails preview Engine which provides a table view for all mails under tmp/mails. So you can easily preview the mails in non-production mode and no longer need to worry about accidentally sending a test email to someone else’s address.

MailsViewer is a fork of tomlion's original code and I'm glad to be the maintainer; thanks go to him for getting this thing started!

REQUIREMENT

  • MailsViewer should be used with Rails >= 3.1

  • In your config file, You should require "sprockets/railtie"if you don't require 'rails/all' and enable assets pipeline by adding config.assets.enabled = true to config file

Usage

Add the gem to your Gemfile :

gem "mails_viewer"

Set ActionMailer's delivery method to :file :

config.action_mailer.delivery_method = :file

put this in your routes.rb:

mount MailsViewer::Engine => '/delivered_mails'

Now just load up http://localhost:3000/delivered_mails

Advanced

You can choose to send out some mails to the inbox instead of just storing them in the file system by specifying which mails to sent:

  • : send_if - Send mails that satisfy some condition
config.action_mailer.delivery_method = :file
config.action_mailer.file_settings = {
  location: 'tmp/mails',
  smtp_settings: {
    address:              "localhost",
    port:                 25,
    domain:               'localhost.localdomain',
    user_name:            nil,
    password:             nil,
    authentication:       nil,
    enable_starttls_auto: true
  },
  send_if: lambda { |mail| mail.destinations.select { |address| ["yedingding@gmail.com"].include?(address) }.any? }
}

Now any mails sent to yedingding@gmail.com will not only store in the filesystem for you to browse later, but also send out to his inbox.
