发送邮件需要 SMTP 到地址

Question

我正在尝试使用 Devise 发送重置密码电子邮件。

错误：

: An SMTP To address is required to send a message. Set the message smtp_envelope_to, to, cc, or bcc address.
from /app/vendor/bundle/ruby/2.1.0/gems/mail-2.5.4/lib/mail/check_delivery_params.rb:9:in `check_delivery_params'

from /app/vendor/bundle/ruby/2.1.0/gems/railties-4.0.2/lib/rails/commands.rb:62:in `<top (required)>'

我尝试手动构建邮件对象：

mail = Mail.new do
  from    'name@mydomain.com'
  to      'name@mydomain.com'
  subject 'This is a test email'
  body    File.read('body.txt')
end

并运行mail.smtp_envelope_to 返回[]。当我运行mail.To = 'name@mydomain.com',mail.smtp_envelope_toreturns["name@mydomain.com"]。

为什么会出现这个错误？

编辑：SMTP_SETTINGS

if Rails.env.staging? || Rails.env.production?
  SMTP_SETTINGS = {
    address: ENV['SMTP_ADDRESS'], # example: 'smtp.sendgrid.net'
    authentication: :plain,
    domain: ENV['BASE_URL'], # example: 'this-app.com'
    password: ENV['SENDGRID_PASSWORD'],
    port: '587',
    user_name: ENV['SENDGRID_USERNAME']
  }
end

编辑：缺少的报价是错误的重新输入。请参阅我的 Rails 代码的 SMTP_SETTINGS。第一个代码块是我试图从控制台重现邮件错误。

Answer 1

原来我认为我移除的 Suspenders 中的 Gem，receiver-interceptor，被留在里面了。

删除解决了问题。
