各位好；
给公司内部配置个邮件服务器，不对外。
以文章http://linuxu.blog.51cto.com/9471357/1641436/作为参考。
目前出现这样的问题:
[root@XTIC ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 XTIC ESMTP Postfix
auth login
334 VXNlcm5hbWU6
334 UGFzc3dvcmQ6
535 5.7.8 Error: authentication failed: generic failure
quit
221 2.0.0 Bye
Connection closed by foreign host.
maillog文件显示：
[root@XTIC log]# tail maillog

这个问题已经困扰我很久了，网上也没有什么明确的解决方案，想请教论坛上的各位大神，有谁能给点建议，谢谢！
