postfix转发邮件时产生退信

fkiori

我有邮件地址 A@gmail.com 和 邮件地址 B@B.com
其中B@B.com是我用postfix搭建的邮箱，该邮箱直接将邮件转发到 A@gmail.com

也就是说，任何发送到 B@B.com 的邮件都会被投递到 A@gmail.com

以前使用一直正常，最近突然发现 A@gmail.com 发到 B@B.com 的邮件会产生退信。
而除了A@gmail.com 以外，其他的地址，发送的邮件都正常，都可以正常到达 A@gmail.com

从日志看，似乎是转发给A@gmail.com 的时候被gmail拒绝了。
怀疑是否google认为这个信是循环的，就拒绝呢？
