我在 centOS 5.4 上安装了 amavis + postfix + spamassassin。“/etc/hosts”文件包含：
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
67.215.65.132 mail.sufalamtech.local mail
当我发送邮件时，出现以下错误：

答案1
您尝试过任何诊断吗？
如果你从命令行查找，会发生什么：
host mail.sufalamtech.local
如果返回“未找到主机”，则表明问题出在 Postfix 之外。例如，/etc/nsswitch.conf 可能仅将 dns 列为主机的解析器。如果您希望它使用主机文件，则 nsswitch.conf 中“文件”必须出现在“主机”旁边。
如果您对 host 命令没有问题，那么可能是 postfix 配置中的某些内容触发了名称服务查找。您使用的是传输文件吗？
在 postfix 邮件列表中，他们总是要求人们发布他们的 postconf -n 的输出，该输出显示配置中默认设置的所有更改。
