Ruby on Rails

It is all fairly well explained in the rails guides however:

If your mailer is on the same box as your web app use something like......

config.action_mailer.delivery_method = :sendmail

config.action_mailer.perform_deliveries = true

config.action_mailer.raise_delivery_errors = true

config.action_mailer.default_options = { from: 'myapp@mydomain.com' }

If the sendmail instance is running on a different box, then you have to use SMTP.

Delete the first line above (:sendmail), and replace with

config.action_mailer.delivery_method = :smtp

config.action_mailer.smtp_settings = {

port: 25, # might be 587

address: 'mymailer.domain.com'

}

Hi Mike, Thank you for your reply,

 We want to configure Redhat Linux and Sendmail / Postfix

Please guide me how to configure via Postfix using my client mailer credentials (they're not providing user name and password)

Thanks & Regards

You need to expand on 'AWS Server'

Do you mean a VM running Linux and Sendmail/Postfix??

Do you mean the AWS 'Simple Email Service'(SES)??

or something else ??

All the configs are different so....

Hi All,

I need to configure SMTP on production,My client only providing address, is that possible without user_name & password to configure SMTP ?

What is your host? If you are using Heroku you can configure SendGrid starter and it will provide a username and password for the mail server it creates for you.

Provision SendGrid like

heroku addons:create sendgrid:starter

Then grab your environment vars with

heroku config:get SENDGRID_USERNAME

heroku config:get SENDGRID_PASSWORD

More information can be found here: https://devcenter.heroku.com/articles/sendgrid 

To use the SMTP mailer you will need to setup an initializer class with something like the following:

So, in config/initializers/setup_mail.rb

ActionMailer::Base.delivery_method = :smtp

ActionMailer::Base.smtp_settings = {

:address => 'smtp.sendgrid.net',

:port => '587',

:authentication => :plain,

:user_name => ENV['SENDGRID_USERNAME'],

:password         => ENV['SENDGRID_PASSWORD'],

:domain => 'heroku.com',

:enable_starttls_auto => true

} 

 Create a mailer template and invoke from your controller of choice and you've got a working mail in production.
