Email Configuration SMTP
config/environments/production.rb
Rails.application.configure do
config.action_mailer.show_previews = false # default: false
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address: ENV['SMTP_ADDRESS'],
port: 587,
domain: ENV['SMTP_DOMAIN'],
authentication: :login,
user_name: ENV['SMTP_USERNAME'],
password: ENV['SMTP_PASSWORD'],
enable_starttls_auto: true
}
end
We can configure the variables with env files. Example:
.env.production:
RAILS_ENV=production
SMTP_ADDRESS=SSM # /dev/demo/SMTP_ADDRESS => email-smtp.us-west-2.amazonaws.com
SMTP_DOMAIN=SSM # /dev/demo/SMTP_DOMAIN => mydomain.com
SMTP_USERNAME=SSM # /dev/demo/SMTP_USERNAME => ABCASD5MXAIYXEXAMPLE
SMTP_PASSWORD=SSM # /dev/demo/SMTP_PASSWORD => ABCunGBKLUdbPdAH/FSxAi8eId99EyAOJz+mxEXAMPLE
The example above maps to an SSM parameter value with JETS_ENV=dev, the default. If JETS_ENV=prod then the SSM parameter would be /prod/demo/<NAME>.
Also, regardless of the value of JETS_ENV, RAILS_ENV=production should always used.
Testing SMTP
One way to test SMTP server connection is with telnet. Example:
$ telnet email-smtp.us-west-2.amazonaws.com 587
Connected to email-smtp.us-west-2.amazonaws.com.
Escape character is '^]'.
telnet> quit
$
Note, to escape out of the telnet session you have to use the escape sequence ^]. That’s the control key plus close square bracket key. Then you can type quit.
