Sytem.Net.Mail.SmtpException Error


If you get the following error:  

System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

Usually, this exception is due to secure connection problem.. 

Gmail has default settings to use "https" while sending emails..  you can change this settings. see attached screenshot.

This should probably fix your secure connection issue.
