Sendgrid在Rails 4上设置

Question

我有一个rails 4应用程序.我设置了ActionMailer,我可以通过localhost和gmail发送订单确认电子邮件.

我在Heroku上安装了Sendgrid并按照设置说明进行操作.我得到了 Net::SMTPSyntaxError (501 Syntax error

我的environment.rb(我在application.yml中有sendgrid用户/ pwd)

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
}

在production.rb - 我唯一的actionamailer设置就是这个.我有这个作为占位符,以便在以后放置真正的域名.我目前正在使用herokuapp.com.

config.action_mailer.default_url_options = { host: 'localhost:3000' }

在我的orders_controller命令创建方法中,我调用下面的内容.

AutoNotifier.orderconf_email(current_user, @order).deliver

auto_notifier.rb

class AutoNotifier < ActionMailer::Base
  default from: "Test Email"

  def orderconf_email(current_user, order)
        @buyer = current_user
        @order =  order
        mail(to: @buyer.email, subject: 'Thank you for your order.')
  end
end

我错过了什么？它适用于使用gmail的localhost,因此我在sendgrid设置或production.rb文件的default_url中缺少某些内容.

Answer 1

对于后代,这是Heroku上Rails中外部SMTP的工作设置:

#config/environments/production.rb
config.action_mailer.smtp_settings = {
    :address   => "smtp.sendgrid.net",
    :port      => 587, # ports 587 and 2525 are also supported with STARTTLS
    :enable_starttls_auto => true, # detects and uses STARTTLS
    :user_name => ENV["SENDGRID_USERNAME"],
    :password  => ENV["SENDGRID_PASSWORD"], # SMTP password is any valid API key, when user_name is "apikey".
    :authentication => 'login',
    :domain => 'yourdomain.com', # your domain to identify your server when connecting
}

更改default from: "Test Email"为有效的电子邮件地址，甚至example@example.com.
