Configuration Settings : Showing An Error "Failed To Set Sender [SMTP: Invalid Response Code Received From Server"?Apr 16, 2011
I have developed flex based application with php. My client is using Windows 2003 Server. I installed IIS Server and Php Installer into my client machine. I configured php into IIS Server and its working fine.
Query: I wrote a mail code for sending mail to my application user. My client is using internal mail server. I want to send a mail through my application. I used smtp.gmail.com into my application and Its working perfectly. But when I am using client internal mail server. It is showing below mentioned error.
"Failed to set sender [SMTP: Invalid response code received from server. (Code: 554, response: Mail from mail-id rejected for policy reasons.]"
