Question

I’m using sendgrid on heroku to send email in production, but would like to send email locally on my mac.

I’ve configured my development.rb a million different ways and keep getting
“Net::SMTPFatalError: 550 Cannot receive from specified address : Unauthenticated senders not allowed”

Spefically, I tried
varying authentication b/w :plain and :login,
tried using my gmail account credentials,
tried using my google app account credentials.

Nothing seems to work, thoughts?

  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.perform_deliveries = true  
  ActionMailer::Base.smtp_settings = {
      :address        => 'smtp.gmail.com',
      :domain         => 'somedomain.com',
      :port           => 587,
      :user_name      => '[e-mail]',
      :password       => 'somepassword',
      :authentication => :plain,
      :enable_starttls_auto => true
  }

I thought I had set the in the production settings (production.rb), it turns out I had set them in environment.rb. Removed it there and everything started working.

Answer 1

I had set the mail settings by accident in the Environment.rb so it was overriding anything I was doing at the production/development config level.
