This project is considered deprecated and is no longer receiving updates. Please use the mail_allowlist gem directly.
This gem is a renamed fork of an existing gem.
MailAllowed is a class you can provide as an interceptor to your Rails app. It ensures only some people are able to receive mails from your app and provides a fallback in case nobody would receive the mail. This can be useful to make sure no accidental emails are sent from your staging environment, but your mails can still be checked.
One way to use it is to set an environment variable MAIL_ALLOWED, check
for its existence and use it to instantiate a MailAllowed so that within
this environment only those email addresses can have mail sent to them.
See below for a code example.
Add this line to your application's Gemfile:
gem 'mail_allowed'And then execute:
$ bundle
Or install it yourself as:
$ gem install mail_allowed
Specify your allowed as an array of email addresses and register them in an initializer in your Rails app. Optionally specify a fallback address as second argument.
Example Rails app initializer using ENV variables:
require 'mail_allowed'
if ENV.key?('MAIL_ALLOWED')
allowed_addresses = ENV['MAIL_ALLOWED'].split(',')
fallback = ENV['MAIL_ALLOWED_FALLBACK']
ActionMailer::Base.register_interceptor(MailAllowed.new(allowed_addresses, fallback))
