SMTP Settings for SendGrid

sendgrid-smtp.rb

# This is what people apparently use:

ActionMailer::Base.smtp_settings = {
  :address        => 'smtp.sendgrid.net',
  :port           => 25,
  :domain         => 'mysite.com',
  :authentication => :plain,
  :user_name      => 'sendgrd_username@mysite.com',
  :password       => 'sendgrid_password'
}

# But if it doesn't work, try:

ActionMailer::Base.smtp_settings = {
  :address              => 'smtp.sendgrid.net',
  :port                 => '587',
  :domain               => 'mysite.com',
  :authentication       => :plain,
  :user_name            => 'sendgrd_username@mysite.com',
  :password             => 'sendgrid_password',
  :enable_starttls_auto => true
}
