Send emails with Padrino in Heroku

heroku, mailing, padrino, ruby

Solution

You should be using one of the parter addons for sending mail with Heroku.

A good option is Sendgrid

`heroku addons:add sendgrid:starter --app=your_app_name`

Then in your Padrino app in app.rb inside your App class:

set :delivery_method, :smtp => { 
  :address              => "smtp.sendgrid.net",
  :port                 => 587,
  :domain               => 'heroku.com',
  :user_name            => ENV['SENDGRID_USERNAME'],
  :password             => ENV['SENDGRID_PASSWORD'],
  :authentication       => :plain,
  :enable_starttls_auto => true  
}

You could substitute these for settings for another external SMTP server, or look at Mandrill for transactional emails.

I suspect the Errno::EPIPE error you were seeing was that it could not connect to a valid SMTP server, so your controller code should be fine as it is.

Problem

I'm trying to send emails via sendmail in Padrino. I did the configuration specified here (Configuration and Quick Usage) But I always get the following error in the server log (on Heroku or localhost): ``` app[web.1]: sh: Illegal option - app[web.1]: Errno::EPIPE - Broken pipe: ``` I installed the `mail gem` and I'm using Padrino 0.10.7 I'm using this, to send the email: ``` post :create do email(:from => "tony@reyes.com", :to => "john@smith.com", :subject => "Welcome!", :body=>"Body") end ``` That's practically all I have...
