Rails 2.3.9和SendGrid，连接被拒绝-本地主机上的connect（2） [英] Rails 2.3.9 and SendGrid, Connection refused - connect(2) on localhost

问题描述

我已经查看了Google和StackOverflow，无法解决这个问题。

I've looked through Google and StackOverflow and can't figure this out.

我有一个使用Ruby 1.8.7的Rails 2.3.9应用程序，尝试像这样通过SMTP发送电子邮件：

I've got a Rails 2.3.9 app using Ruby 1.8.7, trying to send email through SMTP like so:

ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
  :address => "smtp.sendgrid.net",
  :port => '25',
  :domain => "************.com",
  :authentication => :plain,
  :user_name => "***********",
  :password => "**********"
}

我的应用回溯看上去像这样：

My app backtrace looks like this:

推荐答案

我知道了。我的ISP阻止了端口25，所以我不得不更改配置：

I figured it out. My ISP was blocking port 25, so I had to change my configuration:

ActionMailer::Base.smtp_settings = {
  :address => "smtp.sendgrid.net",
  :port => '587',
  :domain => "**********.com",
  :authentication => :plain,
  :user_name => "************",
  :password => "*********",
  :enable_starttls_auto => true
}
