    It looks like you have a problem relaying through your ISP. Have you tested maybe using telnet:

    telnet 25
    helo myhost.mydomain
    If you get any error messages there then it seems like a relay issue with your ISP and you would need to contact them. Maybe they require SMTP auth or your ip range is not allowed to relay through that server ...

    I agree with Gary ..try that telnet stuff.

    Check your /var/log/maillog file contents ...It provides valuable info. about the problem

    And also use gmail ...b'coz yahoo sometimes rejects mails considering it as spam.
