Can you please let me know why you believe you're missing several settings? That screenshot doesn't show anything out of the ordinary to me.
Also, the newsletter respects vBMail's bounced mail setting, so if you're not receiving the newsletter yourself, can you please also make sure your account is not flagged as bounced?
If the scheduled task returns 0, this means it's already processed the newsletter for all users in queue.
Lastly, could you also inspect your server settings to make sure there are no new issues with email delivery?
