Server 2003 Email server: set up DNS to send and receive external email using dyndns services
Posted on 2008-10-25
I am an ex embedded programmer caught in a web of Windows Server 2003 standard edition for non profitable purposes. I have been following discussions for some time now but have not found an answer to my problem so far. I would truly appreciate your help. My server is DC, DNS, DHCP, RA and Email server. Users are able to VPN to the server (certificate PPTP). I am not using Exchange but standard e-mail services.
I do have a dynamic IP address and therefore I have registered at dyndns with xxx.dynalias.net. My local domain is myname.local.
The problem is I am able to send and receive emails locally, but I would like to be able to receive and send also external emails. Well what I basically would like to do is to send emails for firstname.lastname@example.org and translate it at the server site to email@example.com and vice versa.
I have checked with the WireShark external email is arriving to my email server but the username firstname.lastname@example.org cannot be resolved and the server is replying to external host to drop the request.
I suppose there are records I have to set in my DNS, but I do not have a clue how to do it.
Thank you very much in advance.
