Postfix尝试连接到域而不是主机名

我的Postfixconfiguration有几个问题。 让我们从这个开始吧：在Postfix日志中，Postfix尝试连接（SMTP）到example.org而不是mailer.example.org 。 example.org是另一台电脑。

注意：我用我自己的域replace下面的example.org 。 example.org （运行web服务器的计算机）和mailer.example.org （运行postfix的计算机）的DNSparsing是正确的。

试图发送电子邮件的testing：

 ubuntu@mailer:~$ telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 mailer.example.org ESMTP Postfix (Ubuntu) ehlo mailer.example.org 250-mailer.example.org 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN mail from: <[email protected]> 250 2.1.0 Ok rcpt to: <[email protected]> 250 2.1.5 Ok data 354 End data with <CR><LF>.<CR><LF> asdfasdf . 250 2.0.0 Ok: queued as 3AB5A41927 

/var/log/mail.log：

• Postfix转发不起作用
• postfix通过office365问题中继所有邮件
• 转发电子邮件给用户
• 后缀没有更多的空间
• 后缀与dovecot未知的客户端

在提前感谢任何可能的帮助。 我被阻止:(
