Sending emails as company domain from SendGrid
<p>I own a domain, example.com. I'd like to send out emails from my webapp where it displays it's from <em>info@example.com</em>, or <em>support@example.com</em>. </p>

<p>I've used SendGrid a lot in the past from within my websites, but I've always simply been able to fill out where an email is from by editing the <code>From</code> property of the <code>SendGridMessage</code> class, and it just showed up that way on clients.</p>

<p>Is there an official way/API from sendgrid to utilize a domain that I own? What's to stop me or someone else from typing any domain they want using the sendgrid API?</p>
