Postfix 不发送电子邮件,只接收

Postfix 不发送电子邮件,只接收

我最近在我的 Debian 服务器上安装了 PostFix + Dovecot + Mysql,一切运行正常,但我无法发送电子邮件,我在日志中收到错误

NOQUEUE: reject: RCPT from unknown[##.4.##.41]: 454 4.7.1 <#####@icloud.com>: Relay access denied; from=<contato@#####.com.br> to=<#####@icloud.com> proto=ESMTP helo=<air-de-pedro.lan>

在上面的某行我收到了这个警告

warning: hostname ####.virtua.com.br does not resolve to address ###.4.###.41: Name or service not known```

在来这里寻求帮助之前,我查找了所有软件并尝试了所有解决方案,但所有解决方案都有效。
