这个552后面的文字说是被反垃圾给BLOCK了
但是不知道具体是哪里的SPAM 希望各位高手赐教

山坛兄弟

个人的建议如下：
1：如果你的邮件有多个收件人，那么发送失败以后查看日志，看看那个收件人发送失败了，然后在地址本中专门建立一个组，存放发送失败的收信人。
2：检查你的IP是否被列入了国际反垃圾组织的黑名单中，可以在以下的网站查询：http://www.kloth.net/services/dnsbl.php
3：552错误可能是对方自己的反垃圾网关过滤了你的邮件，具体看看退信中是什么内容，是否一致。

IP查询了一下Not listed in这些组织的黑名单中，有可能是对方的反垃圾网关的问题,我这就去查一下
感谢您的回答

可以启用MD的中继转发解决

谢谢楼上的回答　小弟是新手　不解还要麻烦您赐教：
启用ＭＤ的中继　是勾选中继选项里的那几个？
