设计注册确认邮件已发送，但用户看不到这些消息

Question

我在 Rails 申请 Ruby 时获得了设计授权。我添加新用户注册确认，如 manual.

但是新用户收不到确认信息。

确认发送日志表明电子邮件已成功发送：

Devise::Mailer#confirmation_instructions: processed outbound mail in 262.0ms

Sent mail to new-user@email.com (60066.4ms)
Date: Tue, 27 Oct 2015 13:24:12 +0500
From: from@our-mail.com
Reply-To: reply-to@our-mail.com
To: from@our-mail.com
Message-ID: <message-id@my-machine.mail>
Subject: Confirmation instructions
Mime-Version: 1.0
Content-Type: text/html;
 charset=UTF-8
Content-Transfer-Encoding: 7bit

<p>Hello new-user@email.com!</p>    
<p>You can confirm your account email through the link below.:</p>    
<p><a href="http://www.example.com:3100/users/confirmation?confirmation_token=token">Confirm my account</a></p>

但是当我转到新用户的电子邮件时，我没有在任何地方看到确认信，即使在垃圾邮件文件夹中也是如此。我尝试了几个不同的电子邮件提供商 - 结果都是一样的。

我直接从我的应用程序代码发送的另一封信（没有设计）发送和接收成功。

我在 /config/environment/development.rb 中的电子邮件发送设置：

config.action_mailer.default_url_options = {:host => 'www.example.com:3100'}
config.action_mailer.delivery_method = :smtp

config.action_mailer.smtp_settings = {
    :address => ENV['SMTP_ADDRESS'],
    :port => ENV['SMTP_PORT'],
    :user_name => ENV['SMTP_USERNAME'],
    :password => ENV['SMTP_PASSWORD'],
    :authentication => 'login',
    :enable_starttls_auto => true
}

和user型号：

class User < ActiveRecord::Base
    devise :database_authenticatable,
           :registerable,
           :confirmable,
           # :async, # I will enable async when confirmation will work at least in sync mode
           :recoverable,
           :rememberable,
           :trackable,
           :validatable,
           :omniauthable,
           :omniauth_providers => [:provider1, :provider2, ...]

我做错了什么？在哪里可以找到发送失败的原因？

Answer 1

打开 /config/environment/development.rb

并改变

config.action_mailer.raise_delivery_errors = false

至

config.action_mailer.raise_delivery_errors = true

获取电子邮件错误。
