宝石'导轨'，'3.2.12'
宝石“设计”，“〜> 2.2.4”
红宝石：红宝石1.9.3dev（2011-09-23修订33323）[i686-linux]
我尝试了我在网络上可以找到的所有可能的替代/组合，但面临无法摆脱这个错误：Errno::ECONNREFUSED (Connection denied - connect(2)) on Heroku。
我在开发环境中使用了 sendgrid 凭据，它们正在工作并且邮件已成功发送。但是只有在 Heroku 上我遇到了错误。
我能够在端口 587 和 25 上成功 telnet 到 smtp.sendgrid.net。
请在下面找到我的配置/代码片段。
