Question

我查看了Google和StackOverflow，但无法弄清楚这一点。

我使用Ruby 1.8.7获得了一个Rails 2.3.9应用程序，尝试通过SMTP发送电子邮件，如下所示：

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

我的应用回溯看起来像这样：

/Users/jared/.rvm/rubies/ruby-1.8.7-p334/lib/ruby/1.8/net/smtp.rb:551:in `initialize'
/Users/jared/.rvm/rubies/ruby-1.8.7-p334/lib/ruby/1.8/net/smtp.rb:551:in `open'

Answer 1

我明白了。我的ISP阻止了端口25，所以我不得不改变我的配置：

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

Rails 2.3.9和SendGrid，连接被拒绝 - 在localhost上连接（2）
