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： Delivery has failed to these recipients or groups: x@c.com.cn Your message wasn't delivered due to a permission or security issue.
