    Anything in the mail log under /var/log? What do you see when you run
    Code:
    telnet localhost 25
    and then issue
    Code:
    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
    Code:
    postconf -e 'disable_dns_lookups = yes'
    and restart Postfix.
