Many spam filters now catch the majority of junk mail that’s headed your way. Use a different e-mail address to sign up for newsletters, online postings and trade shows. If the inbox begins to bulge with spam emails, you can delete the address. If you didn’t originally sign up to receive an email, or if you don’t recognize the sender, do not unsubscribe from the list. Do not reply to spam, this is what the spammers need, a live email address.”]
