SMTP客户端报354错误不知怎么解决,请高人指点
小弟写了一个SMTP客户端发送邮,但是报345错误，
客户端日志为：
init SNMP Client ................
send:HELO hnzpabc
receive:220 localhost Winmail Mail Server ESMTP ready
send:MAIL FROM:yuto@servicemail.com
receive:250 localhost Winmail Mail Server
send:RCPT TO:hnzpabc@servicemail.com
receive:250 ok
send:DATA
receive:250 ok
send:From:yuto@servicemail.com
receive:354 go ahead, end data with CRLF.CRLF
winmail日志为：
2007/06/13-22:21:27 2560 Connect from 192.168.0.21
2007/06/13-22:21:27 2560 remote helo = hnzpabc
2007/06/13-22:21:27 2560 remote sent 'mail from ' = FROM:yuto@servicemail.com
2007/06/13-22:21:27 2560 mail from = yuto@servicemail.com
2007/06/13-22:21:27 2560 remote sent 'rcpt to ' = TO:hnzpabc@servicemail.com
2007/06/13-22:21:27 2560 rcpt to = hnzpabc@servicemail.com
2007/06/13-22:21:27 2560 smtp data
2007/06/13-22:21:27 2560 go ahead, end data with CRLF.CRLF
我认为是发送邮件内容格式不对但不知怎样改！！！
邮件内容格式为：
from:yuto@servicemail.com
to:hnzpabc@servicemail.com

[解决办法]
smpt客户端得遵循smtp协议
当客户端发送data指令后,服务器回复250 ok指令,这个时候,服务器端就会准备接受邮件正文了
smtp协议中,正文以 '. '结束
服务器发送354 go ahead, end data with CRLF.CRLF
可能是因为客户端上发送的send:From:yuto@servicemail.com格式不对
楼主仔细查看一下关于smpt邮件协议的指令就会清楚了
