Actionmailer not delivering mail, with rails 3

I am trying to make an application, that sends an email when user registers.

i put in the smtp settings for gmail in the config/application.rb file and the mail function l开发者_Go百科ooks like

mail(:to => "me@me.com", :subject => "Mail!", :from => "another@me.com", :content_type => "text/html")

now when i see the logs, i see that it says mail has been sent, but i never receive any mail at all...

also, when i call the mail deliver function, Emails.signed(@user).deliver, the form page does not redirect, but it works if i comment out the email sending code that is either

Emails.signed(@user).deliver

or

mail(:to => "me@me.com", :subject => "Mail!", :from => "another@me.com", :content_type => "text/html")

Thanks :)

Edit: development.rb

App::Application.configure do
  # Settings specified here will take precedence over those in config/environment.rb

  # In the development environment your application's code is reloaded on
  # every request.  This slows down response time but is perfect for development
  # since you don't have to restart the webserver when you make code changes.
  config.cache_classes = false

  # Log error messages when you accidentally call methods on nil.
  config.whiny_nils = true

  # Show full error reports and disable caching
  config.consider_all_requests_local       = true
  config.action_view.debug_rjs             = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.perform_deliveries = true

  # Print deprecation notices to the Rails logger
  config.active_support.deprecation = :log

end

Somewhat late, but nevertheless maybe this will save someone a few hours of head banging. This is probably only relevant to sending emails from gmail. First, in order to help debugging the situation, set the following line in development.rb to true (assuming you're in development mode):

config.action_mailer.raise_delivery_errors = true

This will make ActionMailer not to silently ignore errors. When I did that, I realized gmail is refusing my username and password. I then went to my configuration file where I put all the Action Mailer config directives (for me it was in development.rb, there is probably a better place to put it), and noticed that :user_name was set to "admin" rather than "admin@thedomain.com". Changing it solved the problem. Here is my corrected part of development.rb:

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
  :address              => "smtp.gmail.com",
  :port                 => 587,
  :domain               => 'thedomain.com',
  :user_name            => 'admin@thedomain.com',
  :password             => '<password>',
  :authentication       => 'plain',
  :enable_starttls_auto => true  }

Another thing not to forget: you have to restart the application after making changes in your environment config files. when using passenger this can quickly be missed :)

that's what solved my "problem" when ActionMailer didnt want to send emails without showing any errors..

The things written here did not help me.

I am using Rails 3.2.8 and I spent several hours trying to figure this out and it was very simple in the end. I forgot to call .deliver() on the Mail::Message object that is returned by mail(:to => @user.email, :subject => 'Welcome to the Site') method call.

Just leave everything like it is specified in official RoR tutorial.

That is, in your development/production environment files, make a section like:

  # mailer
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.delivery_method = :smtp

  config.action_mailer.smtp_settings = {
      address:              'smtp.gmail.com',
      port:                 587,
      domain:               'gmail.com',
      user_name:            '<username>@gmail.com',
      password:             '<password>',
      authentication:       'plain',
      enable_starttls_auto: true
  }

And then you subclass ActionMailer::Base, for example like this:

class InfoMailer < ActionMailer::Base
  default from: "<username>@gmail.com"

  def welcome_user_and_send_password(user, password)
    default_url_options = self.default_url_options()


    @user = user
    @password = password
    @url = default_url_options[:host]
    mail(:to => @user.email, :subject => 'Welcome to the Site').deliver()
  end

end

After that, you can simply use this InfoMailer method from your code like a class method:

InfoMailer.welcome_user_and_send_password(user, password)

If you're using the test environment, be sure to comment out this line of code in environments/test.rb:

config.action_mailer.delivery_method = :test
