标题: 发往yahoo.com带附件的邮件,对方老是收不到 [打印本页] 作者: wykk2002 时间: 2011-2-12 12:08 标题: 发往yahoo.com带附件的邮件,对方老是收不到 各位大侠,我使用mdaemon9.52架设的邮件服务器,有固定ip,并且做了反向解析。
发往yahoo.com的邮件有这样一个现象:
不带附件,发送完全没问题,带附件发送,90%会收到一封退信,提示:Socket connection closed by the other side (how rude!)。
我实在是没辙了,请各位帮忙分析一下,如有哪些信息不明,请跟帖提出,我会补充说明,先贴出日志一篇以供分析。

: 邮件包含 [1] 个文件附件

补充说明一下疑问:
1、发往yahoo.com的带附件的邮件,很多时候是会收到以上退信信息,但有时候是能发出去的,为什么?
2、不带附件,很快就能收到,带很小的附件也能收到,我粗略测试了一下,带2M以下的附件基本上都能收到,为什么?
3、上面的日志里面有
Sat 2011-02-12 12:05:18: 发送完成。
Sat 2011-02-12 12:05:21: Socket connection closed by the other side (how rude!)
第一句不是说明发送完成了吗,第二句为什么有这么提示?
4、同时也测试了用163.com,sina.com发往yahoo.com ,163.com很快就能被收到,sina.com的要很久才能收到
5、同时测试用该邮件系统发送邮件给yahoo.com.cn,不存在以上的退信原因,同样的邮件作者: tdk 时间: 2011-2-12 12:47
