SMTP error from remote mail server after RCPT TO:<firstname.lastname@example.org>:
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.
Received: from root by perseus.kit-llc.net with local (Exim 4.80)

Can any one provide some direction on this please?
