Best email practices are:

Do Not

·         Open unknown email attachments. These attachments could infect your computer.

·         Reply to spam. Typically the sender’s email address is forged, and replying may only result in more spam.

·         Fill out forms in messages that ask for personal or financial information or passwords. A reputable company is unlikely to ask for your personal details through email. When in doubt, contact the company in question through an independent, trusted mechanism, such as a verified telephone number, or a known Internet address that you type into a new browser window (do not click or cut and paste from a link in the message).

·         Buy products or services from spam messages.

·         Open spam messages.

·         Forward any virus warnings that you receive through email. These are often hoaxes.
