550-Please turn on SMTP Authentication in your mail client
Hello I am having strange problem. I am trying to send e-mail with php mail() function from my server but each time I am getting an error:
ECDHE-RSA-AES256-GCM-SHA384:256 CV=no: SMTP error from remote mail server after RCPT TO:: 550-Please turn on SMTP Authentication in your mail client.\n550-(web.example.com) [69.87.xxx.xxx]:43902 is not permitted t
The first time when I was testing this I've got a few e-mails inside gmail and after that non of them is sent. Always I get this error.

Use SMTP Authentication by adding a username and password of an email account on your cpanel server into the web form you are using to send.0 -
Hello, Yes, as mentioned in the previous post, check to ensure your PHP script is configured to send with SMTP authentication. Regarding RDNS, you should ask your hosting provider to ensure RDNS is configured for your server's IP address pointing to the server's hostname. Thank you. 0 -
I've got this problem solved, What I am facing now is I can send e-mails to gmail.com for example but when I try to send to other e-mail I get the other error always: SMTP error from remote mail server after initial connection: 554 bosimpinc11 bizsmtp Connection rejected. Reverse DNS for 1.2.3.4 does not exist. Any suggestions on this ? 0 -
