Hello, I created a few emails using WebMail on my hosting and wanted to use the cpanel webmail option to access it. I can send emails without any issues but unable to receive anyone. I tried doing a test from one of my own external emails and this is the error that I'm getting:
550 Please turn on SMTP Authentication in your mail client.mail-io0-f178.google.com[220.127.116.11]:39968 is not permitted to relay through this server without authentication.
Can someone please tell me how can I fix this issue? This is really important for me.
