Devise Mail is not being catched in development environment - ruby-on-rails

Question

I have tried doing authentication using devise in my rails app, I have made use of the 'confirmable' module in devise. However I am able to sign up but i am not seeing any email captured on my mailcatcher user interface. How do I get this problem sorted???
My development.rb is configured as follows
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.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 web server when you make code changes.
config.cache_classes = false
# Do not eager load code on boot.
config.eager_load = false
# Show full error reports and disable caching.
config.consider_all_requests_local = 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
config.action_mailer.default_url_options = { :host => 'localhost: 3000' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {:address => 'localhost', :port => 1025}
# Print deprecation notices to the Rails logger.
config.active_support.deprecation = :log
# Raise an error on page load if there are pending migrations.
config.active_record.migration_error = :page_load
# Debug mode disables concatenation and preprocessing of assets.
# This option may cause significant delays in view rendering with a large
# number of complex assets.
config.assets.debug = true
# Asset digests allow you to set far-future HTTP expiration dates on all assets,
# yet still be able to expire them through the digest params.
config.assets.digest = true
# Adds additional error checking when serving assets at runtime.
# Checks for improperly declared sprockets dependencies.
# Raises helpful error messages.
config.assets.raise_runtime_errors = true
# Raises error for missing translations
# config.action_view.raise_on_missing_translations = true
end

Answer 1

You can use Google Mail as your smtp server.
Replace
config.action_mailer.smtp_settings = {:address => 'localhost', :port => 1025}
With
ActionMailer::Base.smtp_settings = {
:address => 'smtp.gmail.com',
:domain => 'mail.google.com',
:port => 587,
:user_name => 'your#gmail.com',
:password => 'password',
:authentication => :plain,
:enable_starttls_auto => true
}

Answer 2

For me I used the following configuration
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:user_name => "your_gmail",
:password => "your_password",
:authentication => "plain",
:enable_starttls_auto => true
}
Then I opened my email and opened this https://www.google.com/settings/security/lesssecureapps then set it to on.
Remember also to restart your server after editing your development.rb
