目前正在关注第11章的michael hartl的rails教程，帐户激活。我正在使用sendgrid在生产中发送帐户激活电子邮件。但我没有收到电子邮件。代码似乎正在工作，并在heroku日志中生成一个电子邮件模板，但我永远不会发送。在说我的sendgrid帐户未经验证之前我遇到了问题，我已经解决了这个问题。 （除了白色标记阶段，不确定这是否会产生差异）。发送网格帐户未激活，但我仍然在heroku日志中遇到各种错误，我需要帮助来理解它们。
heroku日志：从下面的heroku日志中可以看出。 Testuser1使用电子邮件地址testuser1@testemail.com创建。然后激活电子邮件生成但从未到达（这不是一个真正的电子邮件，但我尝试过多个真实的电子邮件，并得到相同的错误，我只是用这个电子邮件发布在这里）..然后有一些恐怖在结束时我不知道该怎么处理。

这可能是代码问题还是sendgrid设置问题？本教程不会详细介绍如何设置sendgrid。我的发送网格帐户现在处于活动状态，但正如我所提到的，我还没有设置白名单，因为我不知道它是什么。因为我假设没有它，sendgrid将默认为其标准设置。有没有人完成之前的轨道tuto的spart？欢迎任何帮助，谢谢。

要发送电子邮件，您需要配置动作邮件
这是SendGrid official documentation，在how to configure Rails ActionMailer
