Adding an "Attachment Options" Button to a Notes Mail Database for the SecurTrac's Secure E-mail Attachment Delivery Feature
SecurTrac’s Secure E-Mail Attachment Delivery feature can virtually eliminate the possibility of e-mail attachments being filtered or quarantined by external e-mail systems. This is achieved when the outbound e-mail reaches your company perimeter Domino SMTP server that is running SecurTrac. SecurTrac will intercept outgoing e-mails and will relocate any or selected file attachments in the e-mail to a secured storage repository on the Domino server. The e-mail message body is updated to include a secret URL link, where external e-mail recipients can download the attachment(s) via HTTP or securely via HTTPS. To further authenticate the recipients, they can be asked for authentication code when downloading the file attachments. The authentication code is delivered to the recipient by e-mail when requested.
It is possible to add an "Attachment Options" button to a Notes mail database, so that when user uses that mail database to compose a new e-mail from his/her Notes client, he/she can press the "Attachment Options" button to launch a dialog box, which allows he/she to choose whether and what attachments will be replaced with download links, and also capable to control whether verification code is needed to download the attachment. In this guide we will describe how to setup the corresponding SecurTrac configuration and how to add the "Attachment Options" button to a Notes mail database.
Before trying to enable the Secure E-Mail Attachment Delivery feature and adding an "Attachment Options" button to your Notes mail database, you will have to install SecurTrac 2.6 or a later version on your company perimeter Domino SMTP server at first. HTTP task must be running on that Domino server, and that server must be accessible by external Web users. For details about installing SecurTrac on your Domino server, please refer to the SecurTrac Administration Guide.
Configuring the SecurTrac Configuration Database
You will have to setup two SecurTrac Mail Policy documents for the Secure E-Mail Attachment Delivery feature. In addition, you will have to configure the "Attachment settings" in the SecurTrac Server document.
Configuring the Domino Configuration Settings for the Perimeter Domino SMTP Server
Depending on the mail routing topology of your environment, there are chances that outbound e-mails get routed to your company perimeter Domino SMTP server through SMTP/MIME. When this happens, those "SCTAttLink" fields added by the "Attachment Options" button may be automatically removed by the Domino server during mail routing, and hence the SecurTrac's Secure E-mail Attachment Delivery feature may not work as expected. In order to solve that, we need to configure additional settings to instruct your Domino server to generate the corresponding "X_" fields (i.e. the x-headers in the outbound SMTP messages) for those "SCTAttLink" fields.
Adding an "Attachments Options" button to a Notes Mail Database
In order to add an "Attachment Options" button to a Notes mail database, you will have to copy and paste two subform design elements into the mail database by using Domino Designer client.
