Linux 实时监控工具Cisco（RTMT）和Postfix

我正试图针对Ubuntu中的Postfix邮件服务器配置Cisco的实时监控工具（RTMT）。我已经用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，将电子邮件发送到RTMT中的特定地址。 这样做的目的是，每当警报响起时，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中的main.cf文件

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

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

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

使用当前的Postfix设置，您应该能够向

user@nagiosfg3-桌面

，以

用户

身份登录时与客户端一起阅读电子邮件。但我知道这不是你的目标

由于采用了

relayhost

和SMTP协议，您必须将后缀设置为简单卫星。如果有SMTP服务器，您应该使用公司的SMTP服务器

当你提到一个gmail目的地时，你也可以使用它作为中继，多亏了。由于谷歌要求TLS/SSL连接到其服务，因此也必须使用：

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

文件

/etc/postfix/tls\u policy

包含：

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

听起来你已经接近结果了。也许某处有个小错误。请发布有关RTMT邮件配置和后缀设置的详细信息
