日志服务器大量警告：

warning: unable to look up public/pickup: No such file or directory

报错原因：

与Debian Linux VPS 6,你可能得到Sendmail MTA违约。如果你已经安装和配置后缀这可能导致错误。
如果您执行“echo|mail your.com”在本地配置(your.com)你会看到下面的错误出现:
postdrop:warning: unable to look up public/pickup: No such file or directory

解决办法：

关闭sendmail（如果有）然后开启postfix即可！

/etc/init.d/sendmail stop

/etc/init.d/postfix start

ps aux|grep postfix
