email - Ansible 邮件模块发送邮件失败

问题描述

我可以使用以下命令从我的 Linux 主机发送电子邮件：

echo 'These are contents of my mail' | mailx -s 'This is my email subject' -a last2day_access_log catherine@gmail.com

telnet 到 localhost 25 也在同一 Linux 主机上成功连接。

在同一个 linux 主机上尝试了 ansible 邮件模块，如下所示：

- hosts:

     localhost
      tasks:
        - mail:
            host: localhost
            port: 25
            to: 'catherine@gmail.com'
            subject: 'Ansible-report'
            body: 'System {{ ansible_hostname }} has been successfully provisioned.'
          delegate_to: localhost

但是，我收到以下错误：

TASK [mail] ******************************************************************************************

以下是我在 Linux 主机上的主机名：

cat /etc/mail/local-host-names
# local-host-names - include all aliases for your machine here.
mylocalhost

$ uname -a
Linux mylocalhost 3.10.0-1160.11.1.el7.x86_64 #1 SMP Mon Nov 30 13:05:31 EST 2020 x86_64 x86_64 x86_64 GNU/Linux

你能建议吗？

解决方案

根据错误消息告诉您的内容：

SMTPSenderRefused: (553, '5.5.4 <root>... Domain name required for sender address root', 'root')

看起来您的邮件任务实际上是在尝试将邮件发送为<root>，如果您只在本地发送邮件，这可以工作，但很可能会在外界被拒绝。

解决方法是更改​​您的任务并from在您的电子邮件中添加一个正确的：

- mail:
    host: localhost
    port: 25
    from: 'someone@example.org'
    to: 'catherine@gmail.com'
    subject: 'Ansible-report'
    body: 'System {{ ansible_hostname }} has been successfully provisioned.'
  delegate_to: localhost
