After reading through the blogs, I have successfully achieve part of the bounce test in the settings. When I test, I receive the Test-Connection-Bounce email to my bounce email account but the wheel continues to spin and the email is not deleted.
I have confirmed that the email is good, password works, SSL, port, changed the setting in the specific gmail account to allow POP and have tried more and less secure apps in G Suite.
I have also attempted to send a newsletter to two email accounts, one is known good and one is a nonsense email. I receive the newsletter at the good account but no bounce is recorded for the nonsense email by the plugin nor in the bounce email account.
