InterWorx uses the ClamAV software package to detect software threats coming in through the email system.

Enable/Disable SMTP Level Virus Scanning

SMTP level virus scanning allows ClamAV to scan email as it comes in to the SMTP server. This allows ClamAV to stop threats before they ever reach the system. If ClamAV detects a virus it will cause the SMTP service to reject the message.

Enable SMTP Virus Scanning

  1. Click the System Services menu item if it is not already open.
  2. Click the Mail Server menu item if it is not already open.
  3. Click the Virus Filtering menu item.
  4. Locate the ClamAV Options section.
  5. Select Enabled from the drop-down list labeled SMTP Virus Scanning.

If the ClamAV and Freshclam daemons are stopped when you enable SMTP virus scanning, they will be automatically started.

Disable SMTP Virus Scanning

  1. Click the System Services menu item if it is not already open.
  2. Click the Mail Server menu item if it is not already open.
  3. Click the Virus Filtering menu item.
  4. Locate the ClamAV Options section.
  5. Select Disabled from the drop-down list labeled SMTP Virus Scanning.
  6. Click the Update button.

Start/Stop the Clam Anti-Virus Daemon

The stop and start procedures that follow assume that SMTP virus scanning is enabled.

Stop the ClamAV Service

  1. Click the System Services menu item if it is not already open.
  2. Click the Mail Server menu item if it is not already open.
  3. Click the Virus Filtering menu item.
  4. Locate the ClamAV Control section.
  5. Click the Stop button.

If you have SMTP virus scanning enabled and you stop the ClamAV service, mail delivery will stop until the ClamAV service is restarted or SMTP virus scanning is disabled.

Start the ClamAV Service

  1. Click the System Services menu item if it is not already open.
  2. Click the Mail Server menu item if it is not already open.
  3. Click the Virus Filtering menu item.
  4. Locate the ClamAV Control section.
  5. Click the Start button.

Start/Stop the FreshClam Virus Update Daemon

The stop and start procedures that follow assume that SMTP virus scanning is enabled. Freshclam is the automatic virus definition update service used by ClamAV. If this is enabled, ClamAV will always have the most recent virus definitions.

Stop the Freshclam Service

  1. Click the System Services menu item if it is not already open.
  2. Click the Mail Server menu item if it is not already open.
  3. Click the Virus Filtering menu item.
  4. Locate the Freshclam control section.
  5. Click the Stop button.

Start the Freshclam Service

  1. Click the System Services menu item if it is not already open.
  2. Click the Mail Server menu item if it is not already open.
  3. Click the Virus Filtering menu item.
  4. Locate the Freshclam control section.
  5. Click the Start button.
