我看到这样的错误，当启动后缀服务器，也看到maillog时很多失败。 我该如何解决这个问题？

PS运行
postmap /etc/postfix/generic
似乎已经解决了这个问题…
确保前体文件（generic NOT generic.db）存在
ls -la /etc/postfix/generic
当你的错误发生通常这个文件不存在…所以创build它：
touch /etc/postfix/generic
只有这样才会有用处
postmap /etc/postfix/generic
现在您将拥有一个填充文件/etc/postfix/generic.db
我发现在我的/var/log/mail.err，我看到很多这个错误：
postfix / trivial-rewrite [16343]：error：open database /etc/postfix/relay.db：No such file or directory
所以我几乎跟着上面的领先：
这就是诀窍。
