gprs，电子邮件

近几天在试验通过串口助手控制MC55gprs模块发送电子邮件，总是失败，一直找不到原因，有知道的老师麻烦给点建议，谢谢，
设置的gprs模块参数如下，用的是移动卡。
at^sics?
^SICS: 0,"conType","GPRS0"
^SICS: 0,"alphabet","0"
^SICS: 0,"inactTO","20"
^SICS: 0,"user","cm"
^SICS: 0,"passwd","*****"
^SICS: 0,"apn","cmnet"
^SICS: 1,"conType",""
^SICS: 2,"conType",""
^SICS: 3,"conType",""
^SICS: 4,"conType",""
^SICS: 5,"conType",""
OK
使用的是网易126邮箱,XXXXXX@126.COM是发送邮箱，AAAAAA@163.com是接收邮箱
at^siss?
^SISS: 0,"srvType",""
^SISS: 1,"srvType","Smtp"
^SISS: 1,"conId","0"
^SISS: 1,"alphabet","1"
^SISS: 1,"address","smtp.126.com"
^SISS: 1,"user","XXXXXX@126.com"
^SISS: 1,"passwd","*****"
^SISS: 1,"smFrom","XXXXXX@126.com"
^SISS: 1,"smRcpt","AAAAAA@163.com"
^SISS: 1,"smCC",""
^SISS: 1,"smSubj","Hello,this is a test! "
^SISS: 1,"smHdr",""
^SISS: 1,"tcpPort","25"
^SISS: 1,"smAuth","1"
^SISS: 1,"tcpMR","10"
^SISS: 1,"tcpOT","6000"
^SISS: 2,"srvType",""
^SISS: 3,"srvType",""
^SISS: 4,"srvType",""
^SISS: 5,"srvType",""
^SISS: 6,"srvType",""
^SISS: 7,"srvType",""
^SISS: 8,"srvType",""
^SISS: 9,"srvType",""
OK
打开 smtp 服务
at^siso=1  
返回
OK
^SISW: 1, 1  
发送
at^sisw=1,20
返回
^SISW: 1, 20, 0
这个时候发送HELLO
返回
OK
然后就提示错误
^SIS: 1, 0, 400, "SMTP protocol error (500): Error: bad syntax"
126邮箱里面的smtp服务也打开了，邮箱名称也没有错，一直提示错误，不知哪出了问题，烦请知道的朋友指点下，谢谢
如果把126邮箱改为qq邮箱，发送完HELLO后，返回ok   提示连接关闭。搞了了还几天，一直没有进展，希望知道的朋友赐教，谢谢！
