Walled-Garden Add-in for Outlook

A compliance Add-in for Microsoft Outlook to analyse sender lists for recipients outside your organization.

How it Works

The Add-In will extract the sender's (From: ) organization domain to match it against all recipients.

When the email is Sent, all Recipients - in To: , CC: and BCC: - will be matched against the sender's domain.

Any recipient whose domain does not match the sender's will trigger a popup, listing each "outsider" recipient and confirming if the messgae should be send anyway.

Answering No will return to the compose window.

Answering Yes will release the message.
