Preview newsletter received, but trial send does not.

I set up eNewsletter. I can enter the settings and receive both a test email [Root User Test Connection Send] AND the Preview from the email editor (Preview).

When I go to sent to a group though - it says it is is sending, but it does not. In fact it reads that it sent the email, none bounce, none open.

I've simplified things as much as possible (no ssl and turned off CRON) but still have the same result of getting the Test email (from settings page) and the Preview email (from editor page) but not the actual newsletter -

Ideas?
