我的postfix能向外发信，但收不到信，是哪的问题呢？

我的postfix能向外网发信，但是收不到外网的信，日志也没有提示信息。怎么回事呀？
我怀疑是不是sasl验证的问题呀？

fendou_2005

我的sasl验证有问题：25端口不能登陆，但是postfix中把sasl去了就没事。
[root@hwy ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
Connection closed by foreign host.
而去了sasl后就可以

這位兄弟，要把/var/log/maillog貼出來，大家看log才能發現問題啊。^_^

@kang

從你的maillog看是newhero.com.cn服務器拒絕了你的smtp連接請求。
試過從其他的郵箱(比如163的)發過嗎，或者自己發給自己能成功嗎？
可能是postfix main.cf中的
smtpd_recipient_restrictions 和smtpd_sender_restrictions 的設置有問題。

这是我的postfix中main.cf的sasl配置。去了这些收发正常，有这些不能收发。
这是怎么回事呀？
