postfix性能以及是否可以设置优先级队列?

trackless

目前的状况是这样的,队列里有1000封邮件,当我再次发送新邮件时,收件人似乎需要顺序等待所有1000封处理完了,才会收到!这个时候,可能2个小时已经过去了.另一台qmail邮件服务器就没有遇到这样的问题.这是我的第一个疑问!
第二个疑问,是否可以配置特定地址的优先级?

我的main.cf和master.cf配置如下:
main.cf:
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
mail_owner = postfix
myhostname = 省略
mydomain = 省略
myorigin = $mydomain
inet_interfaces = all
mydestination =
unknown_local_recipient_reject_code = 550
mynetworks = 172.29.0.0/16,127.0.0.0/8,172.23.0.3

看来是大公司，邮件队列里面这么多邮件等待处理
