You might want to check some things:
1. Firewall software which may be blocking port 25 (remember that Outlook doesn't use port 25 to send/receive email to Exchange, so firewall software wont neccessarily block this communication)
2. AV software. I know for definate that McAfee V8 and above has 'access protection' rules which prevent telnet on port 25 (I think it blocks telnet on everything except port 23, to be honest). You have to physically stop the McAfee McShield service to get telnet to work again to non-standard ports
3.Are you using any forwarders? if yes disable them.
4. Any IPSEC filtering?
5. Any TCP/IP port restrictions?
6. Is SMTP virtual server up and running? What IP is it bound to?
7. If nothing works you might have to reinstall SMTP after following a MS Knowledge base article.

In McAfee V8 and above, you can add exceptions to processes, which is allowed to use port 25.
If it is a standalone installation, then you should just change it on the client.
If it is an enterprise installation, with EPO Server, then a policy should be modified, and the clients must
get this new policy to handle the exception of course.

Hi I did the Nmap Port scan it say open port .But when i do telnet the curser blink & i can not get any Exchange benner & i can not veryfy wether that is working or not
ASKER
My Windows Firewall is disable & av is also temp disable
uninstall the antivirus and then check
ASKER
I have uninstall the av & reboot the server but no luck same problem
If you logon to the server and starts a commandline,
and then types
telnet <servername> 25
where servername is the name of your mailserver (do not use localhost)
What happens then?
and then types
telnet <servername> 25
where servername is the name of your mailserver (do not use localhost)
What happens then?
okie now try this....
telnet <IP OF YOUR SERVER> 25
check if this works
telnet <IP OF YOUR SERVER> 25
