Errno::ECONNREFUSED: Connection refused - connect(2) for action mailer

Question

I have been working with rails since a long. Now I am facing a small issue in the ActionMailer. I want to send an email when user gets registered to confirm his registration. I am able to send email in the development mode but where as not in the production mode.
the exception Errno::ECONNREFUSED: Connection refused - connect(2) is coming everytime when deliver method is called.
I have written the following code.
My SMTP config looks:
config.action_mailer.default_url_options = { :host => "localhost:3000" }

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true

  config.action_mailer.smtp_settings = {   
    :openssl_verify_mode => OpenSSL::SSL::VERIFY_NONE,      
    :ssl => true,
    :enable_starttls_auto => true,  #this is the important stuff!
    :address        => 'smtp.xxxx.xxx',
    :port           => xxx,
    :domain         => 'xxxxxx',
    :authentication => :plain,
    :user_name      => '[email protected]',
    :password       => 'xxxxxxxxx'
  }

In the controller, I have written the following:

def confirm_registration_in_c       
 @user = User.find_by_email([email protected])
 if @user
      UserMailer.confirm_registration(@user).deliver            
 end
end

In my user_mailer.rb :

class UserMailer < ActionMailer::Base
  default from: "[email protected]"

  def confirm_registration(user)
   @user = user
   @user_name = @user.name       
   email = @user.email 
   mail(:to => email, :subject => "Reset your password")
  end
end

I am able to send email in the development mode in my local host, but I am not able to send the email in the dedicated server.
Can anybody help me please?

Solution 1

In my situation, I encountered similar problems when I was trying to making through a sending-email Rails app tutorial, the Heroku logs kept telling my that

......

Errno::ECONNREFUSED (Connection refused - connect(2) for "localhost" port 25):

......

After I compared my code with author's code, I got to find out that I had not setup my ActionMailer configurations in the config/environments/production.rb file.

Then I came to realized that I just had my config/environments/development.rb configured for sending-email, but I had not done it for my config/environments/production.rb.

So you may check it when your app's behavior difers between development and production.

Solution 2

Be sure you have configured your port correctly. I switched from gmail in development (port 587) to sending from my local server in production and was getting this error till I corrected the port to the one my server uses (port 25).

Solution 3

My problem is not identical to this question, but I feel many would found this thread via google.

If you use external SMTP service like sendgrid and has set up ActionMailer accordingly, yet it still gives this error:

Errno::ECONNREFUSED: Connection refused - connect(2) for "localhost" port 25

You may be passing config hash with String key, which are ignored. Keys must be symbols!

This may happen if it is de-serialized, what I did is to ensure keys are symbols:

config.action_mailer.smtp_settings = get_smtp_setting.symbolize_keys

Solution 4

for production you cant write

config.action_mailer.default_url_options = { :host => "localhost:3000" }

add production url for host, like,

config.action_mailer.default_url_options = { :host => "http://www.yourdomain.com" }

Solution 5

There is another reason for this error:

Errno::ECONNREFUSED: Connection refused - connect(2) for "localhost" port 25

It should be looked at SENDMAIL service on your server:

• Is SENDMAIL installed?
• Is SENDMAIL running?

I had this error due to the stopped SENDMAIL.

Good luck!

did you restart the server after you make change?

[VenkatK]

Yes I have restarted the server after the changes made. But same error.

[Rajendran_R]

login into your gmail account(user_name => '[email protected]'). then restart the server

[Rajendran_R]

Is above mailer settings production.rb or ..?

[VenkatK]

I have written that mailer setting in the /config/application.rb file which is common for all.

[VenkatK]

And I have tried to put that mailer setting in the production.rb but the same issue is coming.

[wetjosh]

I made the same silly mistake. I had added the line config.action_mailer.smtp_settings = { address: "xxxxxxx.xxxxxxx.com" } in app/config/environments/development.rb but forgot to add it to app/config/environments/production.rb.

[fguillen]

Even if this was not my problem it put me in the right direction: my configuration was not being loaded, a console execution of this ActionMailer::Base.smtp_settings was showing me that the values were the default ones

[Roger Perez]

@fguillen how did you fix it? Code?

[Phillip Longman]

I don't believe this person is using Sendmail, so this is not relevant.

[Taika]

I agree with you. But it had solved my problem, so it could be helpful to others. :-)

This helped me go in the right direction. My issue was I had set address: 'localhost' instead of address: '127.0.0.1'.
