can't receive external emails - mx records or blocked port?
Posted on 2008-11-14
OK, I'm having issues sending email from remote clients to my newly installed SBS 2003.
Here is my scenario:
Exchange (single nic) is behind a firewall that has port 25,80,110,443,993, and a couple others pointed to the exchange server.
From outside the office: OWA is working, Web pages are working, email coming in is not working.
From inside the office: I can send email to the outside world without a problem.
I am using godaddy as a host.
I have added an A record to point to myservers ip address:
Host : myserver
Points to: ip address of my qwest router
I have removed the godaddy MX records and made this change:
Priority: 10 (have tried 0 as well)
Goes to: myserver.mydomain.com
I have not changed any of the godaddy standard CNAME entries which include:
At DNSreport.com I have 2 failures:
Fail: Reverse DNS entries for MX records
Fail: Connect to mail servers (however this fails with the standard godaddy info too)
do MX records take a long time to take effect? i have been testing it right after godaddy says it is ready, and for a couple hours after that.
