Working default email setup

When you set up a cloud instance, it's set by default to send email as host@screenconnect.com directly to the recipient's SMTP server.  However, the email doesn't include DKIM and the cloud instances aren't included in the SPF record, which pretty much guarantees that they'll be filtered out.

I appreciate allowing us to configure out own email delivery so we can control where it appears to come from, but this is something that should work by default.
