    Hey guys, Excuse me for being a bit of a noob here.

    My email just starting bouncing this back when I try send mails.

    ------------
    Code:
    This message was created automatically by mail delivery software.
    
    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:
    
      Test@example.uk
       host eu-smtp-inbound-1.domain.com [195.130.xxx.xxx]
       SMTP error from remote mail server after RCPT
    TO:<Test@example.co.uk>:
       550-Please turn on SMTP Authentication in your mail client.
       550-somedomains.com (webhosting2.servername.com) [173.199.xxx.xxx]:43798 is
       550 not permitted to relay through this server without authentication.
    
    --------

    I can still receive emails. I have no idea what 550-somedomains.com is doing there - I never seen that before or heard of it. Anyone any suggestions I would be most helpful - my web hosting is useless at helping me.

    Hi,

    What is the MX record that the domain is using, does it point to you server or other?

    Hello,

    How are you sending the email? For instance, if it's with an email client, do you have SMTP authentication enabled in the client's outgoing mail settings?

    Thank you.
