For most businesses today, e-mail is the

mission-critical communications tool thatallows their people to produce the bestresults.

This greater reliance on e-mail has increased

the number of messages sent and received,the variety of work getting done, and eventhe speed of business itself.

Employee expectations have also evolved. Today, employees look for rich, efficientaccess—to e-mail, calendars, attachments,contacts, and more—no matter where theyare or what type of device they are using.

For IT professionals, delivering a messaging systemthat addresses these needs must be balancedagainst other requirements such as security and

cost.Enterprise security requirements have becomemore complex as the demand and use for e-mailhas increased.

Today, IT departments must contend with e-mailsecurity threats that are wide rangingcontinually evolving spam and viruses,noncompliance risks.

The vulnerability of e-mail to interception andtampering, in addition to the potential harmfuleffects of natural and man-made disasters.



While security is clearly a priority, IT professionalslook for a messaging system that addresses bothenterprise and employee needs while also beingcost-effective to deploy and manage.Microsoft Exchange Server 2007 has been designedspecifically to meet these challenges and addressthe needs of the different groups who have a stakein the messaging system.The new capabilities of Microsoft Exchange Server

2007 deliver the advanced protection yourcompany demands, the anywhere access yourpeople want, and the operational efficiency you, inIT, need.

Server roles allow an administrator to split the functions of anExchange server and place each role, or a combination of

roles, on different servers in the organization. This can be done for performance reasons, managementreasons, or any other reason necessary by the organization'spolicies.With current Exchange servers you can make a server aFront-End server or a Back-End server.

Exchange 2007 introduces five roles to the Exchangeorganization.

MailboxClient Access (CAS)Hub TransportUnified MessagingEdge Transport (Gateway)



Mailbox is the core server, which stores allthe email.Mailbox servers do not transfer messagesbetween mailboxes, for this messagedelivery you need a Hub Transport server.Mailbox role also holds the Exchangedatabases within which the user mailboxesare contained.



The Hub Transport role is responsible for allinternal mail flow.Inbound mail is accepted from the Internet orEdge Transport and passed on to the user'smailbox and all outbound mail is relayed fromthe Hub Transport to the Internet or Edge

Transport and out to the Internet. The Anti-Spam and Anti-virus features can beconfigured on the Hub Transport in order toreduce the number of servers required.



The Client Access server is the server that usersconnect to with their mail client, mobile device, orweb browser.

The Client Access server handles all connections

whether they come from an application such asOutlook 2003 or 2007, Outlook Express, or anyother MAPI, POP3 or IMAP4 client.

The Client Access server also handles connections

made from mobile devices such as a WindowsMobile 5 Smartphone, or any other device usingExchange ActiveSync.



Edge Transport server role is deployed as a stand-aloneserver or as a member server of a perimeter-basedActive Directory domain.Designed to minimize the attacks , the Edge Transportserver handles all Internet-facing mail flow, whichprovides Simple Mail Transfer Protocol (SMTP) relay andsmart host services for the Exchange organization.Additional layers of message protection and securityare provided by a series of agents that run on the Edge

Transport server and act on messages as they areprocessed by the message transport components.

These agents support the features that provideprotection against viruses and spam and applytransport rules to control message flow.



The concept of Unified Messaging is new to

the Exchange product line, and itsintroduction brings with it new telephonyconcepts.Unified Messaging combines voicemessaging, fax, and e-mail into one Inbox,which can be accessed from the telephoneand the computer.Unified Messaging integratesExchange Server 2007 with the telephonynetwork in your organization
