How SafeSend Works
When installed, SafeSend requires validation each time you send an email to an external recipient. You will need to confirm all external recipients of an email before it leaves the network. Upon hitting “Send” or “Send Secure,” the SafeSend pop-up window will appear. To confirm the recipients or any attached file, click on the checkbox beside each of the external recipients (and file if applicable) and hit the Send button.
When you receive your SafeSendArchive-v.r.zip file, it will include the following files:
- Helpful information and links to help you get started
- SafeSendArchive-v.r.m.b.zip (SafeSend PC add-in)
- Administrative Templates
- For use with Group Policy to manage settings when the SafeSend PC add-in has already been deployed
- Admin Password
- Administrative credentials for local access to SafeSend settings
- Not applicable for Trial licenses
- Installer package (.MSI) for the SafeSend PC/COM add-in
- SafeSendWebAddinWeb_v.r.m.b (SafeSend Web add-in)
- End-user License Agreement (EULA)
- Editable file where you add your web server domain
For these instructions, you will need everything within the SafeSendWebAddinWeb_v.r.m.b folder mentioned above.
Install and Configure SafeSend Web Add-in
While SafeSend v4.6 will work with any .NET CORE 3.1 capable web server, we recommend using IIS (Internet Information Services). If using IIS, you'll need to download and install the .NET Core Hosting Bundle found here.
Microsoft requires the site in which the add-in is hosted to be SSL secured.
Deployment of the SafeSend web add-in can take up to 12 hours to propagate the network.
Any changes made to Settings.json require the website to be restarted to take effect. This should be done outside of normal operating hours to avoid potential service interruptions.
