发送某一外网邮件被退信


各位大神帮忙分析分析,情况是这样的:
一个集团n个单位,每个单位都是自建邮件系统,集团也有给全公司的邮件系统,遇到的问题是,A单位a邮箱正常,给B和C单位的b和c发送的邮件被退信,每个邮箱都正常使用,并且这封邮件通过外部126邮箱或gmail邮箱转发,b和c也可以收到。
我分析了一下没找的问题,于是尝试用A单位的一个测试账号向D单位的d邮箱发送相同内容(无附件,是转发的邮件正文),开始也退信,但我从初始的邮件内容一点一点删,发现,删到初始邮件收件人列表的一个邮箱账号时,邮件正文有这个账号就被退信,删去这个账号就正常发送和接收了。于是我将整个邮件去掉这个账号,也正常收发了。
请问大神们,原因是不是就出在这个邮件账号上了?原理是什么?跪谢!!!
以下是退信内容:

我也遇到了同样的问题,环境差不多,我们是子公司自建了邮箱,用总部邮箱给我们发送邮件出现了退信,同时还出现我们收到了总部的邮件但是在几秒钟之后这封邮件又消失了。还在寻找问题,欢迎大家一起讨论,求大神指点。
