请问使用postfix发信到etang信箱错误的问题？

Matteo_NET

我在freebsd上装了个postfix作为邮件的smtp服务器，发信到任何服务器都正常无误。唯独发给etang的信箱，无论是vip信箱还是免费信箱都失败。maillog出错信息如下：
vip信箱：
Jun 22 16:50:42 freebsd postfix/smtp[1064]: 6563B4D0: to=<*****@etang.com>;, relay=mx4.etang.com[61.152.250.179], delay=10, status=bounced (host mx4.etang.com[61.152.250.179] said: 550 System is busy. ZgEAAENu9T5pINS6.1 (in reply to end of DATA command))
免费信箱：
Jun 22 16:57:00 freebsd postfix/smtp[1362]: 68A9B4D0: to=<*****@etang.com>;, relay=mx3.etang.com[61.152.250.171], delay=10, status=bounced (host mx3.etang.com[61.152.250.171] said: 550 System is busy. CwIAAL1v9T5DINS6.1 (in reply to end of DATA command))

任何时候都是system busy。请问如何解决这个问题。

以前在windows下用过一个软件是Mail Express，个人的smtp服务器，在前一个版本无法正确区分vip信箱和免费信箱的mx*.etang.com，所以免费能发，vip的就发不了，后来在新版本中解决了。查看MailExpress 的log，发到vip的信箱连接的是mx3，发到免费的信箱连接的是mx4，但是如果是单独的一封信，发到vip信箱，cc中抄送到免费信箱，或者发到免费信箱，cc到vip信箱，只连接mx3，都能正确发送。

请问这个问题怎么解决？谢谢。

内容很简单subject是test，内容也是test

相同的邮件在Mail Express上发送成功，但是postfix就是不行。

你还是给出原文吧，有可能是Postfix的配置错误，导致MIME编码的时候缺少一些信头而不教严格的系统认为是SPAM

发现一个搞笑的问题，我直接在命令行： mail dimangel@etang.com
随便输入一些subject和正文

发送反而成功了。难道是mutt的问题？

Matteo_NET

找到原因了，是header中的From中的地址的域名和Message-ID后面的域名不相符合的原因，可以被认为是spam了。

但是如果不设From的地址，收信人直接reply就是一个不存在的域名了，晕

Matteo_NET

虽然可以在muttrc中设定
my_hdr Reply_To
但是，如果别人选择添加到地址本，还是一个非法地址，ft

Matteo_NET

只有修改Message-ID: <20030622100520.GA1850@freebsd.matteo.net>; 中的后面的域名了，这个应该是postfix加进来的吧。

该怎么设置呢？

这个是用sylpheed连接本地postfix的smtp发信的记录：

发送成功。

这个是mutt发信的记录：

发送失败。

Mutt是直接讲信放入postfix的mail 队列中，而不是通过连接smtp发信的。所以postfix用了from:<matteo@freebsd.matteo.net>;这样的地址。
该怎么设置postfix？

我想，你是不是手工指定一下下面的相关参数，我是刚学postfix，不太明确，希望你能把测试的结果反馈回来，谢谢，来自/usr/local/etc/postfix/main.cf ：

1. 
   
2. # INTERNET HOST AND DOMAIN NAMES
   
3. #
   
4. # The myhostname parameter specifies the internet hostname of this
   
5. # mail system. The default is to use the fully-qualified domain name
   
6. # from gethostname(). $myhostname is used as a default value for many
   
7. # other configuration parameters.
   
8. #
   
9. #myhostname = host.domain.tld
   
10. #myhostname = virtual.domain.tld
    
11. myhostname = mail.oss4e.org
    
12. 
    
13. # The mydomain parameter specifies the local internet domain name.
    
14. # The default is to use $myhostname minus the first component.
    
15. # $mydomain is used as a default value for many other configuration
    
16. # parameters.
    
17. #
    
18. #mydomain = domain.tld
    
19. mydomain = oss4e.org
    
20. 
    
21. # SENDING MAIL
    
22. #
    
23. # The myorigin parameter specifies the domain that locally-posted
    
24. # mail appears to come from. The default is to append $myhostname,
    
25. # which is fine for small sites.  If you run a domain with multiple
    
26. # machines, you should (1) change this to $mydomain and (2) set up
    
27. # a domain-wide alias database that aliases each user to
    
28. # user@that.users.mailhost.
    
29. #
    
30. # For the sake of consistency between sender and recipient addresses,
    
31. # myorigin also specifies the default domain name that is appended
    
32. # to recipient addresses that have no @domain part.
    
33. #
    
34. #myorigin = $myhostname
    
35. #myorigin = $mydomain
