验证电子邮件不通过Heroku / Mailgun发送

问题描述

我有Rok应用程序在Heroku。它有一个自定义域，我已经尝试通过邮件发送邮件发送。我通过Heroku安装了Mailgun作为附加组件，我已经完成了Mailgun给予的验证我的自定义域。如果我运行Mailgun的现在检查DNS记录，一切都会变成绿色，状态为活动。我甚至可以使用他们提供的 curl 呼叫从我的自定义域发送邮件。但是，当我尝试使用 ActionMailer 从我的Rails应用程序发送电子邮件时，我得到： Net :: SMTPFatalError（554 Sandbox子域仅用于测试目的。请添加您自己的域名，或者在域名设置中将地址添加到授权的收件人。

为什么我认为我使用沙盒子域？这是我在 environments / production.rb 中的内容：

 ＃Mailgun 
 ActionMailer :: Base.smtp_settings = {
 port：ENV ['MAILGUN_SMTP_PORT']，
地址：ENV ['MAILGUN_SMTP_SERVER']，
 user_name：ENV [' MAILGUN_SMTP_LOGIN']，
密码：ENV ['MAILGUN_SMTP_PASSWORD']，
域：'my-custom-domain.com'，
身份验证：：plain， 
} 
 ActionMailer :: Base.delivery_method =：smtp 
＃Devise可恢复
 config.action_mailer.default_url_options = {host：'my-custom-domain.com'} 
  

对于开发我正在使用Gmail，所以我知道它正在阅读正确的配置文件。并且所有的env var都设置正确。从设置正确，我看到我的日志（[email protected]）我错过了什么？有没有什么可以传播，即使是状态是活跃的？

谢谢！

解决方案

所以问题原来是当我验证我的自定义域名时，它在我的Heroku / Mailgun帐户下创建了第二个域名。我还有我的Heroku env vars中的xxx.mailgun.org（沙箱）域的凭据。一旦我用自定义域中的凭据替换了它们，一切工作。 （由于Heroku设置了第一套env vars，我愚蠢地假设新的设置将自动放入。）叹息...

感谢您的帮助。

I have Rails app on Heroku. It has a custom domain, and I've tried to set up email sending through Mailgun. I've installed Mailgun as an add-on through Heroku, and I've gone through the steps Mailgun gives to "verify" my custom domain. If I run Mailgun's "Check DNS Records Now" everything comes back green and the status is "Active." I can even send messages from my custom domain with the curl call they provide. However, when I try to send an email from my Rails app using ActionMailer I get: Net::SMTPFatalError (554 Sandbox subdomains are for test purposes only. Please add your own domain or add the address to authorized recipients in domain settings.

Why does it think I'm using a "Sandbox subdomain"? Here's what I have in environments/production.rb:

  # Mailgun
  ActionMailer::Base.smtp_settings = {
    port: ENV['MAILGUN_SMTP_PORT'],
    address: ENV['MAILGUN_SMTP_SERVER'],
    user_name: ENV['MAILGUN_SMTP_LOGIN'],
    password: ENV['MAILGUN_SMTP_PASSWORD'],
    domain: 'my-custom-domain.com',
    authentication: :plain,
  }
  ActionMailer::Base.delivery_method = :smtp
  # Devise recoverable
  config.action_mailer.default_url_options = { host: 'my-custom-domain.com' }

For development I'm using Gmail so I know it's reading the right config file. And all the env vars are set correctly. The from is set correctly as well, I see it my logs ([email protected]) What did I miss? Is there something that could still be propagating even through the status is active?

Thanks!

解决方案

So the issue turned out to be that when I verified my custom domain it created a second domain under my Heroku/Mailgun account. I still had the credentials from the xxx.mailgun.org (sandbox) domain in my Heroku env vars. Once I replaced them with the credentials from my custom domain everything worked. (Since Heroku set the first set of env vars I foolishly assumed the new set would get put in automatically.) Sigh...

Thanks for your help lyen.
