Answer: B - If a user complains they are receiving a lot of unwanted email in their inbox, you can recommend they use a spam filter.

Key Takeaway: Email spam (otherwise known as junk mail) clutters peoples inboxes everyday-some accounts say there is more spam processed through mail servers everyday than legitimate email. Although it is difficult to control, a spam filter can greatly help a user reduce the amount of this unwanted email. Some services, such as Gmail and Microsoft outlook, have junk or spam filters built in, but depending on the effectiveness of these services and how they are configured, a dedicated spam filter software may be necessary.
