authentication or decryption has failed when sending mail to GMail using SSL

Question

I\'m referring to this guide on C# SMTP mail.

Here is my code:

MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient(\"smtp.gm         


        

Answer 1

If you're using SSL rather than TLS, you need port 465 rather than 587.
