That does sound a bit perplexing all right.

You can send me the url directly if you'd like.

Hi Eric,

Well another interesting factor I come across is that when I used same smarthost from my another qmail toaster server its working fine. Thats making me more confused to rectify the problem. If I provide you with the smarthost can you please check what's its showing at your end.

Thanks and regards,

    I don't know off hand exactly how QMT does authentication with
    smtproutes.

    That being said, 3 common auth methods are plain, login, and
    cram-md5. QMT should only use a method that's shown by the receiving
    server's AUTH reply to the ehlo command. You can check to see what
    the receiving server lists by telnetting to it, and issuing an ehlo
    command. I would check this first.

    If cram-md5 is listed, that's probably what QMT will try to use
    first. I don't know if QMT is programmed to try other methods if the
    first one fails or not. From what you said, I'd guess not. It could
    be either end of the connection though that's not doing/allowing a
    2nd try. The RFC states pretty clearly that subsequent methods may
    be tried should the first one fail.

    I don't know of a way to tell smtproutes to which auth method to
    use. It should be automatic, based on what the receiving server
    shows is available. If you need to use a specific auth method, I
    think you'll need to modify the source code. (I needed to do this
    with the python smtp module a few months ago, which resulted in an
    enhancement to that module. QMT doesn't use that python module though.)

    BL, if the smarthost is showing cram-md5 and can't handle it, it
    should allow subsequent retries. You need to determine whether it's
    QMT or the smarthost that's not doing/allowing retries, and fix
    accordingly. Otherwise, you might modify the QMT source to try plain
    auth first, which I'm pretty sure will work for you.

    Please note, I'm speculating a bit here, but HTH anywise.

        Hi Everyone,

        Some more details which I got after discussing with my ISP on
        the below topic. According to my ISP, the server is sending some
        kind of encrypted password for login authentication but it
        require PLAIN authentication to connect to SMARTHOST.
        I'm not getting where is problem because I'm entering PLAIN
        password in SMTPROUTES.

        Any help.

        Thanks ans regards,

        Amit

           Hi Everyone,

           I'm using smarthost in SMTPROUTES to relay mails from one of my
           qmailtoaster server but its giving me error uanle to authenticate
           remote server with given username and password. But with same
        smart
           host username and password I'm able to send mail from my Outlook
           express.
           My SMTPROUTES file looks like

           :smart_host_server_ip:25 smarthost_username smarthost_password

           Regards,

           Amit
