Connection refused - connect(2) for "localhost" port 1025 - ruby-on-rails

Question

I am going through this tutorial (link:https://www.murdo.ch/blog/build-a-contact-form-with-ruby-on-rails-part-1) to create a simple contact us form on my existing rails application. After completing the tutorial and testing on my development environment I notice that my smtp settings are interferring with my contact us form. Basically I just want send a message to an email address so I dont need the sender mail address for this. I tried removing the SMTP settings in my development.rb file but then I get this error when clicking the submit button:
Errno::ECONNREFUSED in MessagesController#create
Connection refused - connect(2) for "localhost" port 1025
I tried solving in different ways but I come back to this same error. Here's my code:
model/message.rb:
class Message
include ActiveModel::Model
attr_accessor :name, :email, :body
validates :name, :email, :body, presence: true
end
Here's my message controller:
class MessagesController < ApplicationController
def new
#message = Message.new
end
def create
#message = Message.new message_params
if #message.valid?
MessageMailer.contact_me(#message).deliver_now
redirect_to new_message_url, notice: "Message received"
else
render :new
end
end
def message_params
params.require(:message).permit(:name, :email, :body)
end
end
My view:new.html.erb:
<%= form_for #message, url: create_message_url do |f| %>
<%= notice %>
<%= #message.errors.full_messages.join(', ') %>
<%= f.text_field :name, placeholder: 'name' %>
<%= f.email_field :email, placeholder: 'email' %>
<%= f.text_area :body, placeholder: 'body' %>
<%= f.submit 'Send' %>
<% end %>
My Mailer:
class MessageMailer < ApplicationMailer
def contact_me(message)
#greeting = 'Hi'
#body = message.body
mail to: "notifications#example.com", from: message.email
end
end
And my Development.rb/SMTP settings code:
config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
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 => 'localhost',
:port => 587,
:domain => 'localhost:3000',
:user_name => 'example#gmail.com',
:password => '######',
:authentication => 'plain',
:enable_starttls_auto => true
}
I just want to get rid of the smtp settings but unfortunately I cannot, is there any way to override these settings or an alternate solution or am I missing something,
Any help will be appreciated,
Thanks in advance
