Action Mailer Not delivering Emails - MailCatcher and sendmail - ruby-on-rails

Question

I am using Rails 5. I have the following configurations in my config/environments/development.rb and config/environments/staging.rb.
config/environments/development.rb
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = { address: "localhost", port: 1025 }
When I call the method that sends email, I get the following output.
Rendering mailer/consolidated_s3_storage_report.html.erb
Rendered mailer/consolidated_s3_storage_report.html.erb (0.4ms)
Mailer#consolidated_s3_storage_report: processed outbound mail in 17668.1ms
=> #<Mail::Message:86763960, Multipart: true, Headers: <From: mcds#sheridan.com>, <To: mcds.support#sheridan.com>, <Subject: 2017 July - S3 Storage Report>, <Mime-Version: 1.0>, <Content-Type: multipart/mixed; boundary="--==_mimepart_595c962cc36fb_1be1b2198436941"; charset=UTF-8>>
But email is not delivered to my gmail. The 'from' address is 'default from' from which all other emails are sent. Please clarify why my emails are not delivered.

Answer 1

You seem to be using Mailcatcher. Mailcatcher doesn't deliver messages, its to prevent messages from delivering to the actual To email addresses but lets you check of the message is framed correctly. Developers use Mailcatcher in development enviroments to see if the emails are rendered as they expect them to look like without spamming the To email holder.
All the emails that are sent to Mailcatcher can be viewed in a web interface. Visit http://localhost:1080 on your computer, you should be able to see all the emails you send so far from the development environment.

Following is the configuration for send mail to gmail:
config/environments/development.rb
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,
:domain => "gmail.com",
:user_name => "user#gmail.com", #your gmail id
:password => "password", #your gmail password
:authentication => "plain",
:enable_starttls_auto => true
}
