Hi,张工.
1、Maillog最近出现几百行的警告,如下,这是什么原因?
Dec  4 10:25:38 mail postfix/smtpd[14739]: warning: network_biopair_interop: error writing 45 bytes to the network: Connection reset by peer
Dec  4 10:25:38 mail postfix/smtpd[14739]: warning: network_biopair_interop: error writing 29 bytes to the network: Broken pipe

2、客户通过iredmail 发送含PDF附件的邮件,收件人打开附件变成 52a9854110c.txt 类似文件了,我查Log没什么异常。

第一个通常是网关/路由器等设备引起的,google 一下可以看到很多相关帖子。
第二个问题通常是邮件客户端的问题。建议先检查一下收到的邮件源码,看看是否对方发给你的时候就被正确编码了。另外,你是用哪个邮件客户端程序查看邮件?用其它邮件客户端查看同一封邮件是否也出现错误?
