I will do my best to summarize my configurations below. To begin, I am able to send/receive internally on my exchange 2013 CU1 so the mailbox enable accounts I created is good. At first I was not able to receive external email (e.g from yahoo) then I messed around with Receive Connector in EAC and got it to work momentarily. I did a few tests and it work fine until I begin to changed some settings again. Now, I cannot no longer receive external email. I tried to undo what I thought I did, and it is getting no where. Please help....below is my setup:
-domain controller running windows 2012
-another windows 2012 box with exchange 2013 CU1. Machine Name: exch2.kaytech.com IP address 192.168.2.166, internal DNS 192.168.2.161
-ISP IP: 108.202.97.64 (<<I change 1 digit here for privacy). And my ISP do not block port 25
-on my home router I have enable port forwarding to point port 25 to 192.168.2.166
-I registered my domain with godaddy: kaytech.com
So, in godaddy I logged into my account and go to the DNS Manager. In there I have these entries:
A (Host)
@ 108.202.97.64
exch2 108.202.97.64
MX (Mail Exchange)
Priority Host Points to
10 @ exch2.kaytech.com
==============================================
As for my exchange 2013 configurations, I logged into the EAC and under Mailflow--> Send Connector scope SMTP with *. And I picked exch2 as the source server. As for delivery, I chose MX record instead of Smart Host and left the rest default.
Also under Mailflow--> Receive Connector --> I edit Default FrontEnd Exch2-->Scoping Network Binding Adapter, I enter 192.168.2.166 Port 25.
Next, I went into EAC-->Server. I picked my exchange server and edit DNS Lookup with the info below:
External Lookup: Custom setting IP 108.202.97.64
Internal Lookup: Custom setting IP 192.168.2.161
===========================================
At this point, I am so loss so I need your expertise. I would appreciate if someone can point out if I have the correct entries in my godaddy DNS zone as well as my exchange 2013 configurations. I ran the test-servicehealth cmd and everything look good. Thanks
