postfix邮件不能发到外网？
系统Centos5.6，安装了webmin/virtualmin使用postfix，内网互发没有问题，可以接收外网邮件，不能将邮件发出外网，比如发到163，qq邮箱，全部在邮件队列中，贴出邮件发送日记
Jul 30 14:24:13 host postfix/smtp[8897]: 5D76F18897E: to=&&, r...
我有更好的答案
这个是不可以的，只能采用内网的。
已经找到原因了，我的服务器IP不是直接接入而是经路由分配，机房管理员把路由的25端口出口封了只留入口，所有经此路由的服务器均不得发送邮件，只能接收邮件！虽然你不懂，不过问题只有你一个人回答，为了结题，不得不给你了！

单位的邮箱，一到外网后就只能收邮件，不能往外发邮件了，
老是提示如下：'554 5.7.1 &XXXX@***.com&: Sender address rejected: Access denied'。
但在单位内部收发全部都正常。

在单位内网收发邮件正常，一到外网的意思就是指不是在单位内网里面收邮件正常，但是发邮件就不行了，老是是提示
'554 5.7.1 &XXXX@***.com&: Sender address rejected: Access denied'
不知道为什么，求解

mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, www.$mydomain
里面的逗号是否不应该要呢
smtpd_recipient_restrictions = permit_mynetworks 后面加上
permit_sasl_authenticated
我不确定，也一直关注测问题，也不知道，说的能否擦点边。
