Security Hole

Our system has recently started sending out emails through the osproperty component. A possible security hole in the component? Currently, I have shut down all email to and from our server to prevent spam from reaching our subscribers. I have attached a text file of one of the emails we blocked. I can PM backend credentials if need be. Any ideas?

Thanks,

Hi Holden,
What's the version of OS Property? If you are using the version is older than 2.3. Please download and install latest version of OS Property. From version 2.3, OS Property has the feature to integrate with Stopspamforum service. This feature is used to avoid the spam attack through "Sharing" and "comment" forms in property details page.
