有关同一封邮件收到两次、甚或多次(一)

系统RH9+SENDMAIL(8.12.8-4)+MailScanner
硬件配置:P43.0G/1G/Sata160G*2/RAID1
用户:500左右
每天邮件量大概10000封


现在有两个问题让我非常头痛
一。有部分 邮件会重复,原因不明,原来用RHas3+SENDMAIL没有这个现像,现像描述如下:同一时间 同一封会收到两次也有可能三次,但查看一下ID会有一位数不一样,如:
Return-Path: < [email protected]>
Received: from runner-corp.com (runner.com.tw [203.70.67.121])

上面是两封相同的邮件,对发的ID是一样到我这里就变成两封了。

二。接收邮件时经常没响应,因 我公司的邮件比较多,在连接POP3经常会显示60秒超时,在服务器上把等待时间改成2分钟也是没用。但CPU的使用率又不高,正常都有90%以上的空闲。内存会比较紧张一点,物理内存经常会被用掉98%左右。不知道这种问题是否因 硬件性能导致?可否调整系统本身以改善此问题?

三。以web方式读取较大的mail更是奇慢。。。但查看网页的速度好像不会慢。。。。
以上请各位有经验的高手帮忙出谋取划策。我现在是用postfix也不行,用sendmmail也有问题。求求各位了!谢谢!
