Ensure that the Port 25 is not blocked and your IP is not blacklisted.

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.
