postfix 基于系统用户 使用大写用户名时，报错
使用postfix时，基于系统用户的用户名是小写的，使用telnet IP 25 这样的方法，发信没问题
但是当rcpt to:后面出现大写的用户名，回车后就提示 “User unknown in local recipient table”
看日志，没有什么有用的提示，只是提示 mail from:root@zhang.com to W5@zhang.com
不知道为什么，大家没有没好主意？？ 怎么没有人回？？
我又仔细看了下，如果系统中有个小写的用户名，那么信就会发到他里面去
比如发给 L4@163.com的信，会发给 l4@163.com
如果这个小写的用户不存在，就报错， 收件人不在中继列表 这是maillog日志：

这是用户配置文件：
# tail -2 /etc/passwd

这是我telnet到127.0.0.1 25端口时的报错：

这是我的postfix配置文件：

就这样了，请帮忙，谢谢！！ 原帖由 haha_yong 于 2011-11-15 17:43 发表 http://www.5dmail.net/bbs/images/common/back.gif
alias_maps = hash:/etc/aliases 在main.cf里面加上这条试试！
加了之后也是一样的毛病
这句应该是加的别名查询表吧？
