It’s likely that the problem you're having is related to using the "Send from server directly to the email domain SMTP server" setting in the ScreenConnect Administration page's Mail tab. The most reliable method of sending email is to use the "Send through an SMTP relay server" option and specifying your own SMTP server (this can be your own corporate Exchange server, or ISP server, or Gmail, etc.).

Please take a look at HOWTO-0008: Configure advanced SMTP options and let us know if you have any questions (or if this fails to resolve your issue).

*Note that you can also use the “Send from host with a rich mail client (mailto)” option, to send using your local rich email client (e.g., Outlook).

Our licensing is concurrent-based, which means you can have unlimited number of unattended connections and unlimited number of customers waiting in queue. For each active session between a customer and a technician you need one license. We do support pausing and rejoining a session so that you can maximize your license by bouncing between different sessions where the customer is already connected. So, for example, if you need to see two machines at the same time, you would need two licenses; these two licenses sit in a pool and can be used by any member of your team. So one technician could have two simultaneous sessions or two technicians could each have one.

Unfortunately, the ScreenConnect Java client (used by Linux and Mac OS’s) is not yet as fully-featured as the .NET client. Here is a list of the feature differences: INFO-0017: Feature Differences Between .NET and Java Clients.

Please see this post on OpenJDK (and note at the bottom the link to how we’ve addressed this problem in our v2.4 pre-release).

Support Response:
We don’t have a sandbox at this time, but you can set up ScreenConnect on any machine that is stationary. A lot of users utilize an old desktop they have around, or even their work computer. Because ScreenConnect is a self-hosted web application, access to the web app is linked to the external IP address. A laptop that is constantly on the move is not ideal, but if it stays primarily at home or office it would work fine.

Support Response:
We don’t provide anything out of the box, but the ScreenConnect web app is written on top of ASP.NET, and we conform to the ASP.NET authentication model. The Blackshield people may provide a module for ASP.NET you can use with ScreenConnect, or you could write something yourself.
