Allow emailing a user or group at their Ryver site

Given that many people use Ryver and email together in a corporate environment, it would be great if email messages could be forwarded to Ryver users or groups.

For example, if my Ryver site was example.ryver.com and my user was martin, then someone should be able to send an email to martin@example.ryver.com, and it should appear in my personal chat. Similarly, if there was a group called +idle on the site, someone should be able to send a mail to idle@example.ryver.com and it should appear in that group.

The post in either the personal chat or group should retain the attachments as well.
