You need to email Autel tech support. They will email you a document showing you how to setup your email on your device. It's pretty stupid how they configure the email settings, through some sort of 3rd party application.
That being said, for some odd reason, I can no longer send emails from my device, but I can easily receive them. The only way I could send email was to login to www.gmail.com (I have a gmail account) and use the web browser to send emails.
