电子邮件：服务器发送但用户没有收到

问题描述

我正面临一个奇怪的错误。

I'm facing a weird bug.

尝试在用户注册后设置欢迎电子邮件。

Trying to set up welcome email after a user's registration.

根据服务器日志，我的代码发送电子邮件，但用户没有收到。

According to server logs, my code sends an email but a user doesn't receive it.

这是我的代码：

models / user.rb

after_create :welcome_message

  private
    def welcome_message
      UserMailer.welcome_email(self).deliver
    end

和 mailers / user_mailer.rb

def welcome_email(user)
    @user = user
    mail to: @user.email, subject: t("mailer.welcome_email.welcome")
  end

这里是环境。这两个错误发生在他们的

here are environments. The error occurs in both of them

config / environments / development.rb

config.action_mailer.default_url_options = { :host => 'localhost:3000' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  address:              'smtp.mandrillapp.com',
  port:                 '587',
  domain:               'localhost:3000',
  user_name:            '[email protected]',
  password:             'blahblahblah',
  authentication:       'plain',
  enable_starttls_auto: true
}

和配置/环境/production.rb

config.action_mailer.default_url_options = { :host => 'mysite.com' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  address:              'smtp.mandrillapp.com',
  port:                 '587',
  domain:               'mysite.com',
  user_name:            '[email protected]',
  password:             'blahblahblah',
  authentication:       'plain',
  enable_starttls_auto: true
}

我正在使用Devise注册用户。所以，也试图通过以下方式来做到：确认。结果是一样的 - 测试用户没有收到欢迎电子邮件。

I'm using Devise to register users. So, also tried to do that via :confirmable. Outcome is the same – test user doesn't get a welcome email.

Gemfile

gem 'rails', '3.2.12'
gem 'devise', '3.0.3'
gem "mail"

这里是服务器日志

Sent mail to [email protected] (1920ms)
Date: Sat, 10 May 2014
From: [email protected]
Reply-To: [email protected]
To: [email protected]
Message-ID: <[email protected]>
Subject: Confirmation instructions
Mime-Version: 1.0
Content-Type: text/html;
charset=UTF-8
Content-Transfer-Encoding: 7bit

<p>Welcome [email protected]!</p>

最后，[email protected]最终没有欢迎电邮

Yet eventually there is no welcome email at [email protected]

任何想法？

UPD：
在互联网上我看到没有人面临同样的问题
所以，我猜猜我只是错过了一些东西。但是不能弄清楚什么和在哪里。请帮助我。

UPD:on the internet I see that nobody else faces the same problemSo, I guess I'm just missing something. But cannot figure out what and where. Please help me.

推荐答案

尝试这样： -

在config / initializers /文件夹中命名为setup_mail.rb的文件，使其看起来像

Create a file named as setup_mail.rb in config/initializers/ folder so that it looks like

config/initializers/setup_mail.rb

并将以下代码放在该文件中： -

and put the below code in that file:-

ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.perform_deliveries = true
ActionMailer::Base.smtp_settings = {
 :address => "smtp.mandrillapp.com",
 :domain => "mysite.com",
 :port => 80,
 :user_name => "username",
 :password => "blahblahblah",
 :authentication => :plain
}

ActionMailer::Base.default_url_options[:host] = "mysite.com"

从 config / environments / development.rb 和 config / environments / production.rb

config.action_mailer.default_url_options = { :host => 'localhost:3000' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
 address:              'smtp.mandrillapp.com',
 port:                 '587',
 domain:               'localhost:3000',
 user_name:            '[email protected]',
 password:             'blahblahblah',
 authentication:       'plain',
 enable_starttls_auto: true
}
