Rails 4 Sendgrid 集成出错 - 不允许未经身份验证的发件人 [英] Rails 4 Sendgrid integration giving error - Unauthenticated senders not allowed

问题描述

我在 Rails 4 服务器上集成了 Sendgrid 设置.这些设置适用于开发环境.但这在生产环境中会出错.

I have integrated Sendgrid settings on a Rails 4 server. These settings work fine for development environment. But this is giving error on production environment.

Net::SMTPFatalError (550 Cannot receive from specified address <[e-mail]>: Unauthenticated senders not allowed)

config/initializers/email_setup.rb

config/initializers/email_setup.rb

ActionMailer::Base.smtp_settings = {
   :address              => "smtp.sendgrid.net",
   :domain               => DOMAIN,
   :user_name            => ENV['SENDGRID_USERNAME'],
   :password             => ENV['SENDGRID_PASSWORD'],
   :authentication       => "plain",
   :enable_starttls_auto => true
}

config/initializers/devise.rb

config/initializers/devise.rb

config.mailer_sender = '[e-mail]'

config/environments/production.rb

config/environments/production.rb

# Default URL
config.action_mailer.default_url_options = { host: 'mysite.mydomain.com' }

DOMAIN = 'mysite.mydomain.com'

推荐答案

根据 sendgrid 支持团队的说法，当用户名或密码不正确时会出现此错误.我尝试通过 telnet 手动登录到 smtp 服务器，它工作正常.

According to sendgrid support team, this error comes when username or password are incorrect. I tried logging manually into the smtp server through telnet and it was working.

在我的服务器命令行上，我按照以下步骤操作:

On my server commandline, I followed these steps:

telnet smtp.sendgrid.net 587
EHLO
AUTH LOGIN
Enter username in Base64
Enter password in Base64

ENV 变量在我的生产环境中以某种方式不起作用.作为一种解决方法，我尝试直接添加用户名和密码并且成功了.

The ENV variables were somehow not working on my production environment. As a workaround, I tried adding the username and password directly and it worked.
