Error when sending mails with Mandrill in Rails app - ruby-on-rails

I'm having problems with an error when trying to send mails with my App with Mandrill.
I've seen a lot of people have this problem, and I'm sure it has to do with my mailer configuration. See if someone knows how to deal with this, because I'm desperate about it.
ERROR:
Errno::ECONNREFUSED (Connection refused - connect(2)):
production.rb
# Config default action mailer
config.action_mailer.default_url_options = { :host => "localhost" }
config.action_mailer.smtp_settings = {
:address => "smtp.mandrillapp.com",
:port => 587,
:enable_starttls_auto => true,
:user_name => ENV["MANDRILL_USERNAME"],
:password => ENV["MANDRILL_PASSWORD"],
:authentication => 'login',
:domain => 'heroku.com'
}
# Setup for production - deliveries, no errors raised
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.default :charset => "utf-8"

We use Mandrill in production like this:
#config/environments/production.rb
config.action_mailer.smtp_settings = {
:address => "smtp.mandrillapp.com",
:port => "587",
:authentication => :plain,
:user_name => "username",
:password => "API key",
:enable_starttls_auto => true
}
We literally have no other options for Heroku - I think you should remove the default_url_options and domain options

Sendgrid connecting to Rails Issue

Im having issues with using sendgrid with my rails app on heroku. Can anyone tell me what I am doing wrong, or give me any pointers on how I could debug what is going wrong?
my config/environments/production file includes:
config.action_mailer.default_url_options = { :host => 'mydomain.com' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.smtp_settings = {
:user_name => 'apikey',
:password => Rails.application.credentials.sendgrid[:api_key],
:domain => 'mydomain.com',
:address => 'smtp.sendgrid.net',
:port => '587',
:authentication => :plain,
:enable_starttls_auto => true
}
Im getting a 500 error. In my development environment I used the letter opener gem and everything worked great. Thanks in advance.

Ruby on Rails and Sendinblue via SMTP

I would like to use Sendinblue to send transactional email from my Ruby on Rails web application via SMTP.
I edited config/environments/production.rb as follows:
ActionMailer::Base.smtp_settings = {
:address => 'smtp-relay.sendinblue.com',
:port => '587',
:authentication => :plain,
:user_name => ???,
:password => ???,
:domain => 'fireworks.com',
:enable_starttls_auto => true
}
What am I expected to use as user_name and password? My account's username and password or my SMTP keys? Also, am I required to use any gem, like sib-api-v3-sdk, or this gem is useful only for sending email using the Sendinblue API?
This is all you need to use SendInBlue with ActionMailer. Other answers suggest to use gems that are not required for SMTP. You DO NOT need the sendinblue or sib-api-v3-sdk gems to use SIB with ActionMailer in a plain vanilla Rails app.
#config/environments/production.rb
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => ENV.fetch('SMTP_HOST', 'smtp-relay.sendinblue.com'),
:port => ENV.fetch('SMTP_PORT', '587'),
:authentication => :plain,
:user_name => ENV['SMTP_USERNAME'], #See: https://account.sendinblue.com/advanced/api
:password => ENV['SMTP_PASSWORD'], #See: https://account.sendinblue.com/advanced/api
:enable_starttls_auto => true
}
Add this to your gemfile
gem 'sib-api-v3-sdk'
Add this to config/environments/production.rb
config.action_mailer.default_url_options = { host: "your_domain.com", port: 587 }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "smtp-relay.sendinblue.com",
:port => 587,
:user_name => ENV['SEND_IN_BLUE_USERNAME'],
:password => ENV['SEND_IN_BLUE_PASSWORD'],
:authentication => 'login',
:enable_starttls_auto => true
}
Add this in in config/initializers/send_in_blue.rb
SibApiV3Sdk.configure do |config|
config.api_key['api-key'] = ENV["SEND_IN_BLUE_API_KEY"]
end
Make sure your environment variables are correct. It works for me in production.
can add gem 'sendinblue'Official Sendinblue provided API V2 Ruby GEM
In order to send an email, you need to change the smtp settings in config/environments/*.rb(Whichever applicable)
Rails.application.configure do
#append this settings
config.action_mailer.raise_delivery_errors = true
config.action_mailer.perform_deliveries = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => ‘smtp-relay.sendinblue.com’,
:port => 587,
:user_name => ‘YOUR_SENDINBLUE_EMAIL’,
:password => ‘YOUR_SENDINBLUE_PASSWORD’,
:authentication => ‘login’,
:enable_starttls_auto => true
}
end
change STMP & API in Your setting account
STMP SERVER --> smtp-relay.sendinblue.com
port --> 587

SendGrid not sending emails Heroku

I am trying to send mails with SendGrid from my Rails app (using Hartl's tutorial). It didn't work by simply using the addon at Heroku because it needed my credit card. Then I signed up on SendGrid and used my credentials as above, but still no mail. Here above is my production.rb file. Some help, please?
config.action_mailer.delivery_method = :smtp
host = '<https://nameless-sierra-13544>.herokuapp.com'
config.action_mailer.default_url_options = { host: host }
ActionMailer::Base.smtp_settings = {
:address => 'smtp.sendgrid.net',
:port => '587',
:authentication => :plain,
:user_name => ENV['myusername'],
:password => ENV['mypass#'],
:domain => 'heroku.com',
:enable_starttls_auto => true
}
Merci,
In line with the comment above, I believe your values are just a little off. I also believe you need to have a from address set. This is a copy of what I use in production, with your values put in, and it works so hopefully this helps. I do believe that missing a valid from address and the characters in your domain value are why this is not working. Of course, also make sure you have the ENV variables set on heroku.
production.rb
config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { host:'https://nameless-sierra-13544.herokuapp.com' }
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default :charset => "utf-8"
ActionMailer::Base.smtp_settings = {
:from => 'your_email_here#email.com',
:user_name => ENV['myusername'],
:password => ENV['mypass#'],
:domain => 'https://nameless-sierra-13544.herokuapp.com',
:address => 'smtp.sendgrid.net',
:port => 587,
:authentication => :plain,
:enable_starttls_auto => true

to send confirmation email with gmail account.
but, the error in title occur.
I searched many cases similar to my case and tried solutions in there, but those perfectly not worked, so I think my error has some different origin
( what I tried is : 1. less securing myaccount.google.com/u/1/security 2. http://www.google.com/accounts/DisplayUnlockCaptcha)

raise res.exception_class, res.message
end
end
please help me... TT
the problem your gmail setting, you should remove the ENV as you put string directly to it (as my understanding this is your local development this will generate an error since you also put config.action_mailer.raise_delivery_errors = true
config.action_mailer.smtp_settings = {
:authentication => :plain,
:address => "smtp.gmail.com",
:port => 587,
:domain => "mail.google.com",
:user_name => "******#gmail.com",
:password => "******",
:enable_starttls_auto => true
}

Admin notification email failure

I'm trying to send an email to administrator from the production environment, but failing to... It works in development with letter opener gem, but when I try in production, I'm getting the following error:
Net::SMTPAuthenticationError (530-5.5.1 Authentication Required. Learn more at app/controllers/contact_us_controller.rb:8:in `submit_form'
app/models/contact_form.rb:13:in `send_admin_notification'
My code for the submit_form action in the controller is:
def submit_form
#contact_form.attributes = contact_form_params
return redirect_to action: :thanks if #contact_form.save
render :index
end
and the code in the contact_form model is:
def send_admin_notification
AdminNotifier.contact_form(self).deliver_now
end
I've been struggling with this for the past 2 days so any help and guidance would much much appreciated
This works well for me on the production env:
config.action_mailer.smtp_settings = {
:address => 'smtp.gmail.com',
:port => 587,
:domain => 'gmail.com',
:user_name => 'koshlendra#gmail.com',
:password => 'secret_password',
:authentication => 'login',
:enable_starttls_auto => true
}
Try putting these configurations in your production.rb file
config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { host:'yourhost'}
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default :charset => "utf-8"
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'gmail.com',
:user_name => "your email",
:password => "yourpassword",
:authentication => :plain,
:enable_starttls_auto => true
}
