邮件无法通过 php 脚本发送 - VPS 配置存在一些问题

我无法从我的 vps 服务器上的 php 脚本发送任何电子邮件。我去检查日志，发现了以下内容：

这是从 /var/log/maillog 中提取的

现在我真的不明白它们是否代表错误或成功传递，但邮件从未到达邮箱。

这是我的 /etc/hosts 文件中的内容

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.241.188.154 www.myprimarydomain.com myprimarydomain.com

答案1

dsn=5.0.0, stat=Service unavailable

这是一般错误。日志中还指出您的消息已转发至 root@localhost，因此请检查其邮箱以获取更多信息。

我认为您的问题在于您将 localhost 设置为主机名。将其设置为正常：

  1. 将服务器的主机名从 localhost 更改为 FQDN 主机名；
  2. 更新/etc/hosts并添加127.0.0.1 newhostname
