I need help, my forum won't send confirmation emails out and I'm clueless as to what I am doing wrong.

Thanks,

The hostname is obviously invalid. And check the mail logs in your ACP for error messages.

Sorry I gave you the wrong screen shot, reuploading the current settings.

Now I get this:

The mail server does not understand the RCPT TO command. Reason: 550-Please turn on SMTP Authentication in your mail client. 550-linuxweb1.nitrous-networks.eu [185.38.148.82]:53553 is not permitted to 550 relay through this server without authentication.

Could you help instead of closing my other thread please? I really need help
