    SMTP error from remote mail server after RCPT TO:<jim@kit-llc.com>:
    host kit-llc.com [xx.xx.xx.xx]: 550-Please turn on SMTP Authentication in your mail client.
    550-(perseus.kit-llc.net) [192.168.1.1]:48208 is not permitted to relay through
    550 this server without authentication.

    I receive this error when my cPanel host is attempting to send email. I've been searching for the answer for more than a week. It started with a 550 error of trying to impersonate, but following other threads I commented out that portion in the exim.conf file. Now I end up with this and no email going out from the localhost.

    Here is the message body error.
    Return-path: <root@perseus.kit-llc.net>
    Received: from root by perseus.kit-llc.net with local (Exim 4.80)
    (envelope-from <root@perseus.kit-llc.net>)

    As the error message indicates (Please turn on SMTP Authentication in your mail client), have you turned on SMTP authentication in your email client(Outlook, thunderbird etc). You need to enable "My Outgoing Server Requires Authentication" in email client settings.

    Cheers!!!

    Seems you didn't read (or understand) the question thoroughly.

    It is the server (not an email client) sending those emails.

    Usually this error:
    happens when mails is sent to the server where the destination address domain's MX records point to, but in that destination server that domain does not exist in /etc/localdomains, and because of that the email is processed as relayed mail.
    Sometimes this happens because the domain in question exists in both servers (sending and receiving), and the DNS zones of the domain do not match (yes it's a bit confusing to try to explain things like this in generally) .

    Commenting out portions of error messages in exim.conf is not a very good idea. I would suggest you revert those changes, because thats not the solution.

    The reason why it is showing an Internal IP 192.168.1.1 is probably because of what quietFinn has said - i.e. a DNS issue.

    I connect using PHP socket to port 25.

    Forever I send

    MAIL FROM: <mail>

    And FOREVER answer is "OK"

    But FOREVER when I send

    RCPT TO: <mail>

    answer is:

    "550-Please turn on SMTP Authentication in your mail client"

    You say:
    [[[You need to enable "My Outgoing Server Requires Authentication"]]]

    ¿ how I do this ?

    in file /etc/exim.conf ?

    Thanks

    Try configuring your PHP application to use SMTP authentication to send out email.

    Thank you.

    You can check with the developers or documentation of the script you are using to see if an option to use SMTP authentication for sending email is available. Otherwise, you may want to consider consulting with a developer to determine a way to implement this with a custom script.

    Thank you.
