VS API Scanning modes

This section applies only to the Exchange VS API mode

If you have installed GFI MailSecurity in VS API mode, the general settings dialog will contain a VS API tab.

Here you can configure the VS API Scanning mode: You can select the type of VS API scanning mode that you want GFI MailSecurity to use.

GFI MailSecurity supports all 3 VS API scanning modes. These scanning modes are part of VS API. You can select which scanning mode GFI MailSecurity should use from the General options > VS API tab.

The VS API tab is located in the general properties dialog, which can be accessed by right clicking on the general > general settings node and selecting properties. VS API provides 3 scanning modes. Two of these modes, on demand and pro active, are mutually exclusive, where as background scanning can be turned on as an option in either mode.

On demand scanning

In this mode, a new message gets scanned as it gets accessed by the e-mail client. That means there will be a short delay before the user can access the message.

GFI MailSecurity VS API scanning modes

Pro active scanning

In this mode, new messages get submitted to the queue for scanning upon receipt. However if an e-mail client accesses a new message, scanning of this message will receive higher priority.

This is the recommended scanning mode.

Background scanning

In this mode, all EXISTING messages in the store are scanned. This setting will cause GFI MailSecurity to scan all messages in the stores. Depending on how many messages you have in the stores, Exchange & GFI MailSecurity will be very busy for a period of time after enabling this option. If you want to do this, we suggest switching it on the first time during the night, so that the bulk of the scanning work can be done during the night.
