我建立了一个新的 Postfix 服务器并遇到以下问题。当我尝试从另一台服务器使用“邮件”命令发送邮件并且收件人位于另一个域中时,我在 Postfix 服务器的日志中收到“中继访问被拒绝”。
但是,当我使用 Mail 命令或使用 Thunderbird 将其发送到同一域时,它确实有效。
我的理解是,如果服务器位于“mynetworks”中,它应该无需身份验证即可工作,但似乎我做错了什么。

答案1
我确实解决了。我对我尝试过的网络使用了错误的语法
mynetworks = ['127.0.0.1', '192.168.1.0/24']
mynetworks = '127.0.0.1', '192.168.1.0/24'
但它需要是
mynetworks = 127.0.0.1 192.168.1.0/24
即使之前 main.cf 中的评论是
# MYNETWORKS = ['xx.xx.xx.xx', 'xx.xx.xx.0/24', ...]
