554 5.7.1 错误含义
我这边有个用户给Citibank发信时，有时被退信，内容如下：<br><br>
undeliverable to user@citigroup.com<br>
Original message follows.<br>
Received: from TESTpor055beiby mail.test.com with ESMTP(SMTPD32-8.05) id AEDD5D0132;<br>

我查了一下日志，有下面错误，但没查到具体含义和解决方案，不知大家见过没有？<br>

经过分析，我觉得是Citibank Mail spam系统过滤导致的，可能信中存在某些出发过滤的原因。
