How should the DNS and exchange be designed to accept mail from the public to user@mydomain.com pls help me with this Thanks in advance vinay

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.

Your internal domain has nothing to do with e-mail. What matters is your registered domain name(such as www.networksolutions.com)that is associated with a public IP. Inform your ISP to create a reverse DNS for your domain.

Thanks a lot guys. i understood DNS concept but my question is. If i have Domain name mydomain.local and user login to the domain using domainuser@mydomain.local. If i setup the exchange 2010 in the domain(Which can be accessible both Locally and through internet) and mail server address is mail.mydomain.com is it possible for domainuser@mydomain.local to login to exchange whith current credentials. if so how to configure it.

If you configure OWA(Client Access Server), the user should be able to access e-mails in that format. Make sure you have your domain registered properly and translations on your firewall.
