Question

我正在使用Ruby 2.0.0上的Rails 4开发应用程序。该应用程序在Devise注册后发送电子邮件。

这是发送电子邮件的代码：

应用程序/模型/ sponsor.rb：

after_create :send_email_to_admin

private

def send_email_to_admin
    AdminMailer.new_sponsor_email(self).deliver
end

应用程序/邮寄者/ admin_mailer.rb

class AdminMailer < ActionMailer::Base
  default to: '**removed**'

  def new_sponsor_email(sponsor)
    @sponsor = sponsor
    p @sponsor
    mail(subject: "New Sponsor Registration")
  end
end

这是从日志文件中生成的电子邮件：

Sent mail to **removed** (725.5ms)
Date: Mon, 02 Sep 2013 15:01:03 -0400

当我尝试通过创建赞助商来测试代码时，我只是得到了这个错误：

Net::SMTPSyntaxError in Devise::RegistrationsController#create
501 5.5.4 Invalid argument

我的理解是，这通常是因为电子邮件是无效的电子邮件，但我的所有电子邮件都非常简单，格式为name@domain.tld和no-reply@domain.tld。

Answer 1

问题似乎是我在smtp_settings中使用“域”。当我删除它时，我能够从Mailgun和Gmail发送电子邮件

ActionMailer响应“501 5.5.4无效参数”
