Describe an open relay.
What will be an ideal response?
Another major attack involving an SMTP server occurs when an e-mail server administrator does not restrict who can use the SMTP server to send e-mail. This type of configuration is referred to as an open relay. Attackers will scan the Internet looking for open relays that they can use to send spam. This allows the attackers to use the e-mail system to send e-mail anonymously. In the case of worms, malicious software can also use the open relay to propagate itself across the Internet.
