Exchange2003打诊断日志后看到的信息

foggy

Exchange2003邮件服务器。打开诊断日志后看到很多MSExchangeTransport信息，每分钟至少2条，都是说明smtp发送过程中出现的问题，公司邮箱仅30个，而且使用不时很频繁。感觉服务器不是很正常。<br>
<br>
<br>
以下是节选的内容：大家帮忙看看服务器可能存在的问题。<br>
1.<br>
This is an SMTP protocol warning log for virtual server ID <br>
<br>
1, connection #3330. The remote host <br>
<br>
"219.235.237.101", responded to the SMTP command <br>
<br>
"rcpt" with "454 <>: Sender address rejected: Blank <br>
<br>
address is denied! ". The full command sent was "RCPT <br>
<br>
TO:<1225@engma.net> ". This may cause the <br>
<br>
connection to fail. <br>
----------------------<br>
2<br>
connection #3328. The remote host "64.157.4.78", <br>
<br>
responded to the SMTP command "rcpt" with "451 <br>
<br>
VS14-RT5 Mailbox bounce arrival rate exceeds system <br>
<br>
limit (#4.2.2) ". The full command sent was "RCPT <br>
<br>
TO:<fapiao2005@yahoo.com.cn> ". This may cause the <br>
<br>
connection to fail. <br>
---------------------<br>

This is an SMTP protocol log for virtual server ID 1, <br>
<br>
connection #3325. The client at "211.147.232.91" sent a <br>
<br>
"helo" command, and the SMTP server responded with <br>
<br>
"501 5.5.4 Invalid Address ". The full command sent was <br>
<br>
"helo xht.com ". This will probably cause the connection <br>
<br>
to fail. <br>

This is an SMTP protocol warning log for virtual server ID <br>
<br>
1, connection #3314. The remote host "219.146.78.42", <br>
