I am using telerik report server to send email to recipient.But when i configure email setting under report server then it is giving me error:"The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at".
My setting are:
smtp host: smtp.gmail.com
use secure connection : check mark
account name: account name of telerik report server
sender email: my email address.gmail.com
Name: my name
then click on send test email.
Note i have checked the port 465 also.
