    Hello

    On one account emails from external source like hotmail are not arriving. When sent from another account On The vps are arriving fine.

    This error returns.

    "Remote Server returned '550 5.0.350 Remote server returned an error -> 550 authentication required'"

    Any ideas?

    Hi,

    Did you check the exim logs to see why the mail is being rejected? Please check and send in the logs here, so they can be reviewed and discussed further..

    I think they are running it through a third party which might be causing the issue as the error now shows:

    on the top
    rejected your message to the following email addresses:


    Your message couldn't be delivered. When Office 365 tried to send the message, the external email server returned the error below. This is probably due to a problem or policy setting on the recipient's email system."

    and in the bottom of the error message
    gave this error:
    Remote server returned an error -> 550 authentication required
    "

    The exim log contains nothing about this issue

    Hello,

    Could you provide some more information about how you are reproducing the issue? For instance, how is the domain name configured to send email through a third-party?

    Thank you.
