我正在尝试针对 Ubuntu 中的 Postfix 邮件服务器配置来自 Cisco 的实时监控工具 (RTMT)。我已经在 RTMT 中使用 Postfix 的 IP 地址配置了邮件服务器选项，并创建了一个警报以将电子邮件发送到 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。

有任何想法吗？

这是来自 post fix 的 main.cf 文件。

# 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

# Uncomment the next line to generate "delayed mail" warnings

使用当前的 Postfix 设置，您应该能够user@nagiosfg3-desktop在以user. 但我明白这不是你的目标。

relayhost借助SMTP 协议，您必须将 Postfix 设置为简单的卫星。如果有，您应该使用您公司的 SMTP 服务器。

正如您提到的 gmail 目的地，您还可以使用Google SMTP 服务器作为中继，这要归功于SASL 身份验证文档。由于 Google 需要 TLS/SSL 才能连接到其服务，因此也必须使用此文档：

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

以及要包含的文件/etc/postfix/tls_policy：

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