How to use ActionMailer in a Ruby script instead of rails app

I want to write a script that will connect to my email and send emails for me from my laptop terminal using ActionMailer. I'm testing my connectivity to my email server and can't seem to get it to work. For some reason it's still trying to connect to localhost port 25 even though I specified my smtp server and port.

My code:

action.rb

require 'action_mailer'

mailer = ActionMailer::Base.new

# check settings:
mailer.delivery_method = :smtp
mailer.smtp_settings = {
    address:              'auth.smtp.1and1.co.uk',
    domain:               '1and1.com',
    port:                 587,  
    authentication:       'login',
    user_name:            'MY EMAIL ADDRESS',
    password:             'MY PASSWORD',
    enable_starttls_auto: true
  }

# send mail:
mailer.mail(
            from: 'MY EMAIL ADDRESS',
            to: 'MY OTHER EMAIL ADDRESS TO TEST WITH',
            subject: 'test',
            body: "Hello, you've got mail!"
            ).deliver

For some reason I get the following output:

My-MBP:auto_emailer user$ ruby action.rb

You need to specify the delivery_method and smtp_settings options on the class level. Read more at https://api.rubyonrails.org/v6.0.3/classes/ActionMailer/Base.html

require 'action_mailer'

# Specify settings
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
  address: 'auth.smtp.1and1.co.uk',
  domain: '1and1.com',
  port: 587,
  authentication: 'login',
  user_name: 'MY_EMAIL_ADDRESS',
  password: 'MY_PASSWORD',
  enable_starttls_auto: true
}

# Send email
ActionMailer::Base.new.mail(
  from: 'MY_EMAIL_ADDRESS',
  to: 'ANOTHER_EMAIL_ADDRESS',
  subject: 'Testing from Ruby script',
  body: "Hello, you've got mail!"
).deliver
