Question

我正在尝试从Cisco配置Ubuntu中的Postfix邮件服务器的实时监控工具（RTMT）。我已经使用Postfix的IP地址在RTMT中配置了邮件服务器选项，并创建了一个警报，以便将电子邮件发送到RTMT中的特定地址。这样做的目的是每次警报响起时我都想收到一封电子邮件。我可以使用mailutils命令发送邮件，但无法在RTMT和Postfix之间进行通信。

有什么想法吗？

这是post fix修复的main.cf文件。

# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

使用当前的Postfix设置，您应该能够向user@nagiosfg3-desktop发送电子邮件，并在以user身份登录时与客户端一起阅读电子邮件。但我明白这不是你的目标。

由于relayhost和SMTP协议，您必须将Postfix设置为简单卫星。如果有的话，您应该使用公司的SMTP服务器。

当您提到gmail目的地时，您也可以使用Google SMTP server作为中继，感谢SASL authentication documentation。由于Google要求TLS / SSL连接到其服务，因此也必须使用this documentation：

relayhost = [smtp.gmail.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_tls_policy_maps = hash:/etc/postfix/tls_policy

在/etc/postfix/sasl_passwd中，您将设置您的Gmail帐户用户名和密码，以便Google允许您的Postfix将其服务用作中继：

[smtp.gmail.com]  username@gmail.com:yourpassword

要包含的文件/etc/postfix/tls_policy：

[smtp.gmail.com]:587  encrypt protocols=TLSv1 ciphers=high
