postfix性能以及是否可以設(shè)置優(yōu)先級(jí)隊(duì)列?

trackless

目前的狀況是這樣的,隊(duì)列里有1000封郵件,當(dāng)我再次發(fā)送新郵件時(shí),收件人似乎需要順序等待所有1000封處理完了,才會(huì)收到!這個(gè)時(shí)候,可能2個(gè)小時(shí)已經(jīng)過(guò)去了.另一臺(tái)qmail郵件服務(wù)器就沒(méi)有遇到這樣的問(wèn)題.這是我的第一個(gè)疑問(wèn)!
第二個(gè)疑問(wèn),是否可以配置特定地址的優(yōu)先級(jí)?

看來(lái)是大公司，郵件隊(duì)列里面這么多郵件等待處理
