I just wanted to say I finally figured out the issue with google. I used your settings above, but still received a POP error. I had to make a change in Google's settings to allow "less secure apps" to sign in.
Log in to Google, go to your account, go to "connected apps and sites" and on the right side, scroll until you see "allow less secure apps" and turn it on.
Once I did that, the email finally worked!
