[求助]webmail无法发信到外网

nothing9

Apache2 + MySQL + PHP + postfix（虚拟用户）+ Courier-IMAP/POP3 + SquirrelMail

webmail在本域内收发信件一切正常，但是发信到 [email protected] 时squirrelmail提示：

Transaction failed
Server replied: 554 <[email protected]>: Relay access denied.

请问：这是哪里限制了往外发邮件？

发送 mail 时，直接调用 sendmail 程序，看看

echo "test" | mail [email protected]

21cn邮箱可以收到邮件。

gugong

我正是这个意思，叫你的 webmail 直接调用 sendmail 程序

gugong老大的意思，我不太明白。难道要修改 squirrelmail 的源代码？

现在的main.cf如下，webmail提示的 Relay 是否就是这里的 relayhost 呢？
