It was pain in the *ss for me also to configure the email settings.
BUT...
Here is THE hint I did realize and worked for me :
using gmail smtp server :
SMTP Server : smtp.gmail.com
SMTP Server port : 587
Sender : myname@gmail.com
Receiver : myname@gmail.com
Username : myname@gmail.com
Password : "mygmailpwd"
STARTTLS option checked.
Now..... THE thing missing in this thread is TO CHANGE YOUR GOOGLE ACCOUNT SECURITY SETTINGS !!!
Going through https://myaccount.google.com, you have to active the "less secured apps" access option.
It immediately worked for me.
I hope it will help you to not trash your camera !
