Ruby on rails ActionMailer“；Net:：ReadTimeout“；使用机架空间延迟作业时“；emailsrvr.com“；

编辑：我正在使用Rails 3.2.17和Ruby 2.0.0p0

我在发送邮件时遇到了一些问题，比如

ActionMailer

超时；看

将默认的

Unicorn

timeout增加到2min（用于测试）后，它大约在45秒内完成。我认为最好的处理方法是使用

延迟作业

，然而，当DJ运行

交付

方法时，它也超时了。堆栈跟踪如下

DJ是这项工作的合适工具吗？我是否需要增加DJ的超时时间（我以为我读到的默认值是6小时）？任何建议都会有帮助

DJ呼叫：

NotificationsMailer.delay.access_granted(self).deliver
