Is my MX record configured correctly? My domain is parked with godaddy.com. At that site, I have changed my MX and A records to point to the static IP of my router. When I "nslookup -q-mx domainName.com" I get back the correct "mail exchanger" name ( mail.mydomain.com ) But the ip address of mail.mydomain.com does not display. ( an IP address does display when I run nslookup on microsoft.com ) thanks, Here is the output of nslookup -q: C:\Users\steve>nslookup -q=mx mydomain.com Server: UnKnown Address: 192.168.1.28 Non-authoritative answer: mydomain.com MX preference = 0, mail exchanger = mail.mydomain.com C:\Users\steve>nslookup -q=mx microsoft.com Server: UnKnown Address: 192.168.1.28 Non-authoritative answer: microsoft.com MX preference = 10, mail exchanger = mail.messaging.microsoft.com mail.messaging.microsoft.com internet address = 65.55.88.22 What do I need to do to complete my exhange server 2010 config and start to receive email? Exchange 2010 is installed. My MX record is pointing

Try testing from an external source like MXToolbox: http://www.mxtoolbox.com/ What does it return? Have you tried sending and receiving email? If so, any NDRs?Tim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

Hi Steve, http://www.testexchangeconnectivity.com/ is a great website for verifying mail flow. If you navigate to this website and select the inbound mail option and follow the on screen instructions, this should help point you in the right direction. Also, does your public DNS A record of mail.mydomain.com point to your routers global IP address? If you ping mail.mydomain.com from your workstation does it return the IP address you expect? In addition, bare in mind that public DNS changes can take some time to fully propagate. Kind Regards.

I am installing exchange to learn what it takes to config an email server. So far I have: - a static IP from the ISP ( verizon fios ) - registered a domain thru godaddy.com - installed exchange 2010 on windows server 2008 R2. That server is running active directory, sql server. - configed the cisco 520 router to forward port 25 to the server : 192.168.1.28 - changed the A to point to the static IP of my router> - changed the MX record to mail.mydomain.com What do I do next? Do I need the UCC/SSL certificate to receive mail thru the web? When installing exchange I did enter "mail.mydomain.com" for the client access something or other. My active directory/server domain is store.MyDomain.com . Are there config steps needed for linking mail.mydomain.com , store.mydomain.com and mydomain.com ?

a certificate is not needed for email traffic. You need to allow port 25 inbound and outbound of your firewall. You will need to create a port translation over port 25 (for SMTP) and port 443 (for Web Services, not requried for mail flow) to your Exchange server. You will need to create a receive connector to accept email from the internet. You will need to create a send connector for outbound email.

what was missing for me on this was an "A" record at the godaddy hoster of my domain. I had to delete a CNAME record named "mail" and add an A record named "mail" with the static IP of my router. The answers I got to my questions were outstanding. I greatly appreciate it.
