 大家好，我的服务器系统为freebsd+postfix+qpopper+openwebmail，支持smtp认证，从昨天开始发现系统不正常：
1，postmaster账号收到大量的以下信件或类似的Postfix SMTP client:errors from *****的信件。
在不断增加。
Postfix SMTP client: errors from mail1.954access.net[216.235.97.254] 完全邮件头
Unexpected response from mail1.954access.net[216.235.97.254].
Transcript of session follows.

2，/var/spool/postfix/ 目录下的defer/、deferred/、incoming/目录被大量占用，远远超出邮件服务器的正常使用量。并且在不断增加。
