Create a Accepted Domain mydomain.com New-AcceptedDomain -DomainName Contoso.com -DomainType Authoritative -Name Contoso http://technet.microsoft.com/en-us/library/aa995975.aspx -- Now Create a Email Address Policy You can use Console , So that you can understand better http://technet.microsoft.com/en-us/library/aa996800.aspx -- Now Mailboxes are ready to receive new domain emails if these things are already done . Thats good -- Public IP , Resolving mydomain.com Should NAT to Exchange 2010 Server -- Exchange Should point the internal DNS server. That should be sufficient and recommended Satheshwaran Manoharan | Exchange 2003/2007/2010 | Blog:http://www.careexchange.in | Please mark it as an answer if it really helps you

DNS for email delivery: http://exchange.sembee.info/network/dnsconfig.asp Don't use the root of the domain for anything other than a public web site. You will also need autodiscover.example.com in the public DNS. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.

hi, >>>if i have a registered domain name mydomain.com and the internal domain name mydomain.local. How should the DNS and exchange be designed to accept mail from the public to user@mydomain.com In external DNS you should add one MX record of the mydomain.com domain, it should point to your HUB server, if you have edge, it should point to your edge server. If you want to use autodiscover, you need the third record for autodiscover like Sembee say. Internal DNS, you should add an A record for your exchange server. This can help your clients in your AD domain find your exchange server. hope can help you thanks, CastinLu TechNet Community Support
