我的vServer是旧的（Plesk 8.6，openSUSE 10.3，Qmail）。 它会在几个月内被replace，但我需要一个解决scheme，直到那时。
由于约。 两个月发送电子邮件变得更慢。 如果您想用电子邮件客户端发送电子邮件，则必须等待一分钟或更多时间。 在同一台服务器上有一个web应用程序，每天通过PHP函数mail（）发送〜1000（进程）电子邮件。
Plesk经常演示，smtp服务没有运行。 但是qmail-send进程正在运行一个邮件队列中的邮件被发送（慢）。 qmail-send进程不需要这些资源，top显示一个介于0.4和2之间的负载。
但其他发送邮件之间有相关性。 如果qmail在邮件队列（本地或远程）中有其他邮件，速度将下降。 如果邮件队列是空的，PHP邮件（）需要大约。 一秒钟，当有更多的邮件邮件邮件需要10-60秒。 如果我两次调用php脚本，第一个邮件将会发送得更快，第二个邮件发送更慢。
在邮件stream量高的时候，延迟会增加。 如果邮件是从web应用程序或外部邮件客户端创build的，则不重要。
我检查了名称服务器，反向DNS，如果qmail将启动与-Rt0参数。 没有证书参与。 一些邮箱是6演出大。
我没有更改qmail的并发设置，因为即使邮件队列中只有一个邮件，也会出现问题。 而第一封邮件也不慢，只有一秒钟。
/ var / qmail / handlers / spool中有〜200个月大的邮件。
有人知道什么是错的？
