Ensure you trust the sender and be cautious of any links or attachments. - If you have any doubt about an email's legitimacy, do not release it and contact the IT helpdesk for advice. - Emails detected as standard junk mail are sent directly to the Junk folder in your mailbox, not to quarantine. - Once a sender is blocked, you will no longer receive quarantine notifications for emails from that address.
