postfix无法向外部发送邮件。

linuxnewers

centos系统，刚配好的postfix，用客户机的OUTLOOK在内网收发邮件都正常，接收外部邮件也正常，但就是无法发送。小弟是个实实在在的菜鸟，请各位大虾多多帮助，在此感激不尽。我把相关配置文件发出来，指点指点。

怎么没人回阿，，， 自己顶一个，大虾们快来阿。

Sep  3 13:41:02 localhost postfix/smtp[9096]: fatal: open database /etc/postfix/generic.db: No such file or directory
显示没有没有发现/etc/postfix/generic.db文件
估计你建立了/etc/postfix/generic却没有生成DB文件

你尝试一下   postmap /etc/postfix/generic 会生成generic.db
然后重新启动postfix

另外问一下，你要做的是单一domain还是有虚拟domains的系统？

说真的，邮箱系统自己玩玩就算了，用个成品的吧！如iredmail kerio


kerio我用的就不错！但要管理好，也需要比较扎实的邮件知识。如rbl spam bind等。

就是这个咯“fatal: open database /etc/postfix/generic.db: No such file or directory
”

用成品邮箱其实感觉不推荐的，安全问题不好把握。  还有客户许多定制的需求不好满足。  现在给客户用的都是postfix+各种其他组件
