You work as the enterprise administrator at ABC.com. ABC.com has a domain named ABC.com. The ABC.com network servers run Microsoft Windows Server 2008 and the client computers run Microsoft Windows Vista. ABC.com has a computer named ABC-SR17 configured to host the SMTP service and Internet Information Services (IIS) Web server role.

ABC.com has a Marketing division which uses ABC-SR17 to send and receive email to and from the Internet.

How would you configure ABC-SR17 to ensure mail for the Internet is sent to the Internet Service Provider (ISP) mail server?

A.
By running the adprep/dm: getfromiis command.

B.
By configuring smart host setting to employ the mail server of the ISP.

C.
By configuring smart host settings for the local host to use.

D.
By configuring the SMTP delivery setting opening ports assigned by the ISP for SMTP service.

Explanation:
You need to set smart host setting to use the ISP mail server. A smart host server helps you in delivering all your mail. IT processes bounce-backs, retries and general mail delivery. Due to the processor-intensive nature of the mail delivery system with millions of spam messages, a server can get overwhelmed processing mails. It doesn’t have enough time to do normal web serving. To address this issue, you should use smart host on your ISP mail server to manage the mail delivery and the related tasks.
