通过将testing计算机IP设置为mynetworks = IP，您可以看到通过系统得到更远的邮件，但是会呛匹配类。 如何强制Postfix匹配任何IP源/目标域的0.0.0.0？

仅供参考， 454 4.7.1 <[email protected]: Relay access denied; 是defer_unauth_destination的结果。 与reject_unauth_destination稍有不同，拒绝意味着代码为550的永久错误，延迟意味着代码为450的临时错误。
但是等等…，我没有任何使用defer_unauth_destination的参数。 奇怪的限制来自哪里？
实际上，postfix有一个叫做smtpd_relay_restriction 隐藏限制参数。 这是新的function，所以较旧的教程可能不会涵盖它。 默认情况下， smtpd_relay_restriction具有值
# postconf smtpd_relay_restriction permit_mynetworks, permit_sasl_authenticated, defer_unauth_destination
所以，这解释了defer_unauth_destination的位置
但它没有回答我的问题，我的客户被拒绝:(
（defer | reject）_unauth_destination的行为是postfix手册页中的文档。
reject_unauth_destination
拒绝请求，除非下列条件之一成立：
- Postfix是邮件转发器：已parsing的RCPT TO域匹配$ relay_domains或其子域，并且不包含发件人指定的路由（user @ others @ domain），
- Postfix是最终目的地：已parsing的RCPT TO域与$ mydestination，$ inet_interfaces，$ proxy_interfaces，$ virtual_alias_domains或$ virtual_mailbox_domains相匹配，并且不包含发件人指定的路由（user @ others @ domain）。
简单来说：postfix会检查收件人的地址 。 如果域部分未在relay_domains （或其子域），$ mydestination，$ inet_interfaces，$ proxy_interfaces，$ virtual_alias_domains或$ virtual_mailbox_domains中定义，则postfix将拒绝它 。
在上面的日志中，收件人是[email protected]，所以很明显为什么postfix拒绝它。
我用THUNDERBIRD作为MUA，而且我也有同样的问题。 我解决了在main.cf的mynetworks参数上添加我的家用PC的IP地址
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 MyIpAddress
PS我没有一个静态IP为我的家用电脑，所以当我的ISP改变它，我大约每次调整。
