Anything in the mail log under /var/log? What do you see when you run telnet localhost 25 and then issue ehlo localhost?

Looks ok. Anything related to this issue in your mail log?

I don't think this is an Outlook (Express) issue... although using Thunderbird or alike surely wouldn't hurt....
Check if your Postfix is doing DNS reverse lookup or IDENT lookups on hostnames it cannot resolve. This may introduce delays of 30 secs or so from what I have seen

I think so, But I don't know how to disable doing DNS reverse lookup

Run
postconf -e 'disable_dns_lookups = yes' and restart Postfix.
