我知道有一堆这样的问题。 但没有人有这里描述的相同的情况。 这是情况。
我有一个静态IP。 我在虚拟机中设置我的postfix邮件服务器。 我的静态IP是在我的服务器的一个接口中定义的。 我的服务器也是我的虚拟机主机。 我有一个MASQUERADE在我的iptables中跳转到我的服务器的两个接口之间。 总之，我的服务器有2个接口。 其中一个使用静态公有IP，另一个使用静态内部IP（192.168.1.0/24）。
我的postfix邮件服务器由IP 192.168.1.4标识。 我能够接收来自外部的电子邮件并在内部发送电子邮件。 但是，我所有发送给外部邮件提供商（yahoo，hotmal，gmail ..）的电子邮件都以未送达方式返回。 看来电子邮件正在出去。 它没有被拒绝（我认为）。 已经被发送后被反弹。
是什么让我这样想是邮件日志。 正如您在下面的日志中看到的，带**的行表示电子邮件已发送。

这些域是在mysql数据库中configuration的。 对于域我有以下几行：
+-----------------------+-----------+---------+ | domain | transport | enabled | +-----------------------+-----------+---------+ | mail.thegeekbeaver.ca | virtual: | 1 | | thegeekbeaver.ca | virtual: | 1 | +-----------------------+-----------+---------+
我也有一个内部的DNS。 DNS服务器是由我的服务器托pipe的其他虚拟机。 我的DNS服务器的IP是192.168.1.3。 它负责翻译内部名称。 如果不能翻译，则转发给我的ISP DNS。
这里是我从gmail回来的消息作为例子
This is the mail system at host mail.localdomain. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message. The mail system <[email protected]>: mail for gmail.com loops back to myself Reporting-MTA: dns; mail.localdomain X-Postfix-Queue-ID: 7199212037D X-Postfix-Sender: rfc822; [email protected] Arrival-Date: Sun, 16 Jun 2013 11:00:35 -0400 (EDT) Final-Recipient: rfc822; [email protected] Original-Recipient: rfc822;[email protected] Action: failed Status: 5.4.6 Diagnostic-Code: X-Postfix; mail for gmail.com loops back to myself
看看Diagnostic-Code: X-Postfix; 。 它没有告诉内部电子邮件。 告诉我，Gmail回环我的电子邮件。
这些是我的iptables规则：
#Allowing Established Sessions iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT #connections from inside network iptables -A INPUT -i lo -j ACCEPT iptables -A INPUT -i p3p1 -j ACCEPT iptables -I INPUT -p tcp --dport 25 -j ACCEPT iptables -I INPUT -p tcp --dport 143 -j ACCEPT iptables -I INPUT -p tcp --dport 110 -j ACCEPT iptables -I OUTPUT -p tcp --dport 53 -j ACCEPT iptables -I OUTPUT -p udp --dport 53 -j ACCEPT iptables -A OUTPUT -p tcp --sport 25 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --sport 143 -m state --state ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --sport 110 -m state --state ESTABLISHED -j ACCEPT #PREROUTING iptables -t nat -A POSTROUTING -j MASQUERADE iptables -t nat -A PREROUTING -p tcp --dport 25 -j DNAT --to 192.168.1.4:25 iptables -t nat -A PREROUTING -p tcp --dport 143 -j DNAT --to 192.168.1.4:143 iptables -t nat -A PREROUTING -p tcp --dport 110 -j DNAT --to 192.168.1.4:110 iptables -A FORWARD -i p2p1 -p tcp --dport 25 -d 192.168.1.4 iptables -A FORWARD -i p2p1 -p tcp --dport 143 -d 192.168.1.4 iptables -A FORWARD -i p2p1 -p tcp --dport 110 -d 192.168.1.4 iptables -A FORWARD -i p2p1 -p tcp --dport 53 -d 192.168.1.3 iptables -A FORWARD -i p2p1 -p udp --dport 53 -d 192.168.1.3 #iptables -A FORWARD -j DROP iptables -A INPUT -j DROP
我相信这是我所有的细节。 我相信你会尽力帮助我。 但是，请相信，这不是一个神秘的问题。 请不要回答我说我必须与我的目标价值观一起工作。 问题不在于此。 我确定。 当错误与mydestination值相关时，后缀诊断代码将显示一个内部域。 除此之外，这不是一个备用电子邮件。 这不是一个中继服务器。 它是一个主邮件服务器。 当我有一个dynamic的IP时，相同的configuration工作正常。 当我将其迁移到静态解决scheme时，它停止工作。
我的问题是，为什么外部电子邮件已发送，但提供商拒绝它，并回到我的邮件服务器？
问题不是外部供应商拒绝你的邮件，而是你使用iptables拦截所有 25端口上的stream量，然后redirect到192.168.1.4:25 ，这当然是你的后缀安装。
这就是为什么你会收到错误的邮件回到自己，因为它是从字面上回到自己。
我设法通过以下方式解决：
iptables -t nat -A PREROUTING -p tcp -i eth0 -d 177.53.80.39 -dport 25 -j DNAT -to-destination 192.168.0.111:25
