It's all done already, and this particular username/password is the one allowed to pass through all that, and I'm getting my messages through - except that it's using Outlook and Outlook's own security features jump in. I'm wondering if there's a way with wwipstuff to send email with login, but without using an email client (such as Outlook or whatever).
