使用邮件发送邮件挂起 - Ubuntu 14.04

我尝试使用 ubuntu shell 发送电子邮件，当我执行以下命令时，会话被挂起。请帮助我。

echo“你好，世界”|邮件-s“主题”[电子邮件保护]

一段时间后，终端会抛出以下消息。

邮件：无法发送消息：进程以非零状态退出

要诊断mail失败原因，请尝试以下操作：

  • ~/.mailrc在编辑器中打开
  • 确保它包含行set verbose
  • 保存并退出
  • 尝试echo "hello world" | mail -s "a subject" [email protected]

您应该看到详细的输出——我的看起来像这样：

查找任何错误 - 在我的例子中，有以下两行：

050 504 5.5.2 <vagrant-ubuntu-trusty-64>: Helo command rejected: need fully-qualified hostname
050 554 5.5.1 Error: no valid recipients

因此邮件被拒绝，因为我的主机没有完全合格的主机名。

编辑：您还可以检查/var/log/mail.log/是否/var/mail/<yourusername>有有关错误的有用信息。
