Didn't you ask this on IRC not long ago? Whether the SMTP AUTH extension is offered on a plain connection before STARTTLS is not universal; that depends on the SMTP server. I would advise you to review your provider's SMTP setup documentation. If they have made a change, it should be reflected there. Once you've determined what authentication your provider requires, we can see how to configure mailer.py for it. Cheers, Daniel
