 Autolab requires mailing to allow users to register accounts and reset passwords. You will also be able to make announcements through Autolab as well. The recommended approach is to setup Autolab to use a SMTP server, such as [mailgun](https://mailgun.com), [SendGrid](https://sendgrid.com), [Amazon SES](https://aws.amazon.com/ses/) or any other valid SMTP mail servers to send out email.
