在CentOS 6.2框中，我有兩個Postfix實例，稱爲postfix和postfix-bounce，通過the multiple instance setup document on Postfix's site進行設置。當我通過init.d腳本（service postfix start）手動啓動它們時，它們工作正常。Postfix和CentOS - 在啓動時不啓動多個實例
但是，當我重新啓動服務器，不管我做什麼，無論是設置服務啓動，或在/etc/rc.local裏把「後綴的開始」，它將無法成功啓動第二個實例：
Apr 6 22:09:19 server postfix/postfix-script[1246]: starting the Postfix mail system
Apr 6 22:09:19 server postfix/master[1247]: daemon started -- version 2.6.6, configuration /etc/postfix
Apr 6 22:09:20 server postfix-bounce/postfix-script[1256]: fatal: the Postfix mail system is already running
多實例配置在/etc/postfix/main.cf文件：在/etc/postfix-bounce/main.cf
multi_instance_wrapper = ${command_directory}/postmulti -p --
multi_instance_enable = yes
multi_instance_directories = /etc/postfix-bounce
multi_instance_group = mta
多實例配置：
multi_instance_group = mta
multi_instance_name = postfix-bounce
multi_instance_enable = yes
multi_instance_wrapper = ${command_directory}/postmulti -p --
我在做什麼錯？
