Hello,
I configured PMG in Cpanel for inbound email filter. I get following error when send an email.
Diagnostic-Code: smtp; 550-Please turn on SMTP Authentication in your mail
client. 550-domain.tld [xx.xx.xx.xx]:45482 is not
permitted to relay 550 through this server without authentication.
What should I do? Thank you.
