    Please post the exact error message(s) from your mail log.
    What's the output of
    Code:
    netstat -tap
    and
    Code:
    hostname -f
    , and what's in /etc/hosts and /etc/resolv.conf?

    the test says we are in blacklist what should we do?

    Contact the maintainers of every single blacklist that you are on and ask them to remove you.

    1) goto http://www.mxtoolbox.com/blacklists.aspx , and enter your server IP
    2) when the status is: "Listed", you need to click on the "Blacklist Name" that is infront of it (in your case it's "FIVETENFREE, FIVETENIGNORE, FIVETENKLEZ, FIVETENMULTI, FIVETENOPTIN, FIVETENOTHER, FIVETENSINGLE, FIVETENSRC, FIVETENTCPA and FIVETENWEBFORM")
    As all the Blacklist Names are the "same" list, you will only need to contact the owner once.

    You will find more info on how to contact the list when you have clicked on one of the Blacklist Names.

    You will also find more info at the top of the page saying "We notice you are on a blacklist. Click here for some suggestions."

    fr0m_heaven's suggestion does also work: http://www.dnsstuff.com/tools/ip4r.ch?ip=210.4.3.71

    Same thing again as above. You will need to contact the owner of the list

    thank you

    thanks for the information, i send an email and waiting for their reply

    My friends domain is also on the blacklist on http://www.mxtoolbox.com/blacklists.aspx, but they can send email without any problem.

    I doubt if being blacklisted really our problem, i'm so confuse, still i can't send an email, but can receive easily.

    hello

    hello! i just check my ip if it still on blacklist, fortunately, were not listed anymore.

    but still we can't send a message on email, that means being blacklisted is not the main reason why we can't send a message.


    please help me to configure my sendmail, thanks.

    Do you have this problem only when you try to send a mail to a Yahoo account, or with other email accounts as well?
    IS your server hosted on a dynamic IP address?

    Most email providers such as Yahoo, Hotmail, Gmail, etc. block mail servers that use dynamic IP addresses. That's why you have these problems.
    You can relay your mails through a mail server on a static IP address: http://www.howtoforge.com/postfix_relaying_through_another_mailserver
