Question

我正在SMTP上使用heroku run rails console服务器发送电子邮件，但收到了一些错误。但它在本地系统上工作得非常好，无法理解问题所在。

代码：

message = <<MESSAGE_END
From: Jobs<notification@example.com>
To: Ajay Gupta<ajaygupta@example.com>
Subject: SMTP e-mail test

This is a test e-mail message.
MESSAGE_END

Net::SMTP.start('SMTP_URL') do |smtp|
  smtp.send_message 'message', 'ajaygupta@example.com', 'ajaygupta@example.com'
end

错误：在heroku控制台上运行上面的代码时

Net::OpenTimeout: execution expired

根据您的呼叫heroku run rails console显示您尝试在基于Heroku的服务器上运行此功能。根据Heroku自己的docs，您只能使用外部服务发送电子邮件，例如SendGrid或其他提供商。

无法从heroku控制台发送eamil
