SomeThing Wrong with Mail Relay

[shernyeexing]

Our exchange server is monitered by MailRelay .
last friday , the Mailrelay returned a Bad Status with Reply "SMTP:".
we checked our exchange server, but all service(pop3\smtp\imap) was ok.
then i copy this Test to a new machine, the status is ok.
then i reboot the old machine, restart the HM, and reset the test, but the status is still bad.
on the old machine, i can telnet 110, 25, . but why the status is still Bad?

the setting of the TEST:
outgoing server: smtp:mail.xxx.net
incoming server: pop3:mail.xxx.net
sender/recepient: testmail@xxx.net - testmail@xxx.net
smtp port 25
pop3 port 110
alert when incoming mail server doesnot receive mail before next checking cycle.

We are checking our code for version 8.86...
So far it looks like HostMonitor was able to login to your mail server (outgoing server) but server did not accept e-mail for some reason and server did not send valid error description.
Could your check smtp:mail.xxx.net server logs?

You answered this question by yourself.

no error/warn logs on smtp server.

testmail@xxx.net can recieve the mail by HM like this:
HMRelayTestID 73 63108
This is MailRelay test mail
