[ Rails + AWS + sendmail: Emails not being sent even with (seemingly) correct config settings? ]
So in my development my emails are sending fine when I change the settings. However in my preview environment on my server, in the logs it looks like emails are sending properly with no errors, but I never receive anything. This applies to not just one mailer, but all of them.
This is my config/environments/preview.rb file:
EdmundWeb::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
# Code is not reloaded between requests
config.cache_classes = true
# Full error reports are disabled and caching is turned on
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.perform_deliveries = true
# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = false
# Compress JavaScripts and CSS
config.assets.compress = true
# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = false
# Generate digests for assets URLs
config.assets.digest = true
# Defaults to nil and saved in location specified by config.assets.prefix
# config.assets.manifest = YOUR_PATH
# Specifies the header that your server uses for sending files
# config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
# config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx
# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
# config.force_ssl = true
# See everything in the log (default is :info)
config.log_level = :debug
# Prepend all log lines with the following tags
# config.log_tags = [ :subdomain, :uuid ]
# Use a different logger for distributed setups
# config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)
# Use a different cache store in production
# config.cache_store = :mem_cache_store
config.action_view.cache_template_loading = true
config.cache_store = :dalli_store, 'localhost', { :namespace => 'preview' }
# Enable serving of images, stylesheets, and JavaScripts from an asset server
# config.action_controller.asset_host = "http://assets.example.com"
# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
# config.assets.precompile += %w( search.js )
# Enable threaded mode
# config.threadsafe!
# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation can not be found)
config.i18n.fallbacks = true
# Send deprecation notices to registered listeners
config.active_support.deprecation = :notify
# Log the query plan for queries taking more than this (works
# with SQLite, MySQL, and PostgreSQL)
# config.active_record.auto_explain_threshold_in_seconds = 0.5
# For Devise
config.action_mailer.default_url_options = { :host => 'mysite.com' }
config.to_prepare { Devise::SessionsController.force_ssl }
config.to_prepare { Devise::RegistrationsController.force_ssl }
config.to_prepare { Devise::PasswordsController.force_ssl }
end
In my environment.rb I set my mailer to sendmail:
# Load the rails application
require File.expand_path('../application', __FILE__)
# Initialize the rails application
EdmundWeb::Application.initialize!
ActionMailer::Base.delivery_method = :sendmail
Could it be mailer settings on my AWS server that is preventing my mailer from sending mail?
Answer 1
My AWS machine was running on ubuntu. The fix was running apt-get install postfix
as root and accepting all the default answers. How is this not documented anywhere else!
