我无法让我的 qmailtoaster 在 CentOS 5.9 64 位上工作：
[root@nowosci supervise]# qmailctl stat
authlib: up (pid 2653) 212 seconds
clamd: up (pid 2658) 212 seconds
imap4: up (pid 2663) 212 seconds
imap4-ssl: up (pid 2652) 212 seconds
pop3: up (pid 2667) 212 seconds

imap4/log: up (pid 2664) 212 seconds
imap4-ssl/log: up (pid 2654) 212 seconds
pop3/log: up (pid 2660) 212 seconds
pop3-ssl/log: up (pid 2657) 212 seconds

smtp/log: up (pid 2661) 212 seconds
spamd/log: up (pid 2650) 212 seconds
submission/log: up (pid 2662) 212 seconds
发送已关闭。手动运行时我得到：
[root@nowosci send]# ./run
alert: cannot start: unable to switch to queue directory
这里有什么问题吗：
[root@nowosci /]# ls -l /var/qmail/
razem 48K

drwxr-xr-x 2 root qmail 4,0K lut 18 23:56 users
还是这里？
[root@nowosci /]# ls -l /var/qmail/queue/

解决方案很简单，删除所有 qmail 包然后删除旧用户和组：
然后重新安装 qmail 包，一切正常；）
