邮件开始发送时出现异常终止

huaren801007

情况是这样的，两台邮件服务器需要转发邮件,从MDeamon向Exchange转发的过程中，发送数据的瞬间被Exchange端突然终止,在MDeamon的日志记录如下:
Tue 2007-05-29 19:41:44: [532:4:2] --> MAIL From:abc@xxx.com SIZE=8486
Tue 2007-05-29 19:41:44: [532:4:2] <-- 250 2.1.0 abc@xxx.com....Sender OK
Tue 2007-05-29 19:41:44: [532:4:2] --> RCPT To:<123@xxx.com>
Tue 2007-05-29 19:41:44: [532:4:2] <-- 250 2.1.5 123@xxx.com
Tue 2007-05-29 19:41:44: [532:4:2] --> DATA
Tue 2007-05-29 19:41:44: [532:4:2] Socket connection closed by the other side (how rude!)
Tue 2007-05-29 19:41:44: [532:4:2] Winsock Error 10053 Software caused a connection abort.
Tue 2007-05-29 19:41:44: [532:4:2] Unexpected socket closure
Tue 2007-05-29 19:41:44: [532:4:2] SMTP session abnormally terminated, 539 bytes transferred.

不知道什么原因,敬请各位指教

另外,我从Exchange上没有看到关于123@xxx.com这个帐户接收邮件的日志,请问有没有办法可以看到,或者是可以记录下象MDeamon这样详细的记录

对任何建议,表示衷心感谢!
