Lost input channel from ...

[herzel]

Hi
I do support Solaris 8 machine that was installed on it Sendmail version "11.8.0,REV=2000.01.08.18.12"(output from pkginfo -l)
I did ask to from my manager to make this box to receive mails from outlook.
So I did added the following line to senmail.cf :
"O DaemonPortOptions=Port=smtp,Addr=140.6.20.22, Name=MTA"
When 140.6.20.22 is my host IP Address.
It worked fine after our exchange admin did some changes in the exchange config and all was good.
Suddenly without anything obvious mails stopped reaching from outlook to this machine, although other hosts not experiencing any kind of this or else problem.
I did look at the mail.log and below is the output:
Can anyone help?
Can anyone point to something, give suggestion or clue?
Any response will be highly appreciated!


the output from the log:

Hi
Can anyone look at above?
Look like not very problematic case for the repliers at this forum.
I did check at Google and it says something about spammers.
Any help, advice, clue will be highly appreciated!
