554 5.7.1 中繼存取被拒絕後綴

我在從 cyberpanel rainloop 發送電子郵件時遇到問題。我正在 mx 工具箱上進行測試，它的顯示

Status Ok   SMTP Reverse DNS Mismatch   OK - 170.64.156.12 resolves to mail.kacktus.com.au
Status Ok   SMTP Valid Hostname OK - Reverse DNS is a valid Hostname

這是後綴配置：

non_smtpd_milters = $smtpd_milters

tls_server_sni_maps = hash:/etc/postfix/vmail_ssl.map

我花了很長時間尋找解決方案，但無法弄清楚。我正在使用 digitalocean Droplet 和 cyberpanel。

錯誤訊息準確地說明了它不起作用的原因。 MX Toolbox 正在嘗試使用您的伺服器作為中繼，但您的伺服器不允許中繼。

如果你想成為一個開放中繼（你不應該想要的)，您可以添加0.0.0.0/0到您的mynetworks，但為了從 MX Toolbox 進行測試，您可以臨時設定它。

前段時間我做了一個簡單的 Ansible 角色來設定 Postfix 伺服器，你可能會從中獲得有用的資訊：https://github.com/polatsinan/postfix_server

特別是查找templates/main.cf.j2文件。
