Hello everyone,
First off, I would like to state that I have around five years of Microsoft Server experience, but I have never set up an Exchange environment from scratch, and my knowledge in that area is admittedly not so great. So if there are any areas of my questions that are either incorrect or going in the wrong direction, I would appreciate your help in getting pointed in the right direction :-)
So for some background, I have my own Windows Server 2012 R2 environment set up, consisting of a primary and secondary domain controller, and my newly set up Exchange 2013 SP1 server (making for a total of three servers).
After some struggle, I was able to get my Exchange server set up and configured to the point where I can send and receive emails internally. I have followed step-by-step guides that I found on TechNet to accomplish this, so I am fairly certain that I have set up at least all the basics correctly, such as Mail Flow and Send / Receive Connectors.
Here is where my inexperience comes into play, however. I purchased / reserved a domain through GoDaddy in the hopes of using it as the @domainname.com portion of my email address. I set up my @domainname.com portion of my email addresses to match the domain name that I purchased, and as I mentioned I am able to send and receive internally (which is obvious, since it is internal and hasn't actually gone out to the Internet yet.)
So now I am trying to figure out how to both send emails to external destinations (testing it using my gmail account), and to receive emails back from the same gmail account. When I sent off a test email, I checked the message queue and discovered that the email I tried to send was stuck in a loop where it was trying to be resent, and the only error message that displayed was:
The last attempt to send the message was at 4/9/2014 10:16:26 AM (UTC-05:00) Eastern Time (US & Canada) and generated the error '[{LRT=};{LED=};{FQDN=};{IP=}]'.
I have searched and looked at numerous blogs and articles that potentially address this error/issue, but so far have been unable to figure out a solution to be able to send/receive externally.
For the receiving part, I am uncertain what exactly I need to do on the GoDaddy hosted domain side to make it so that emails will get routed over to my Exchange server, so I would also appreciate any help on this step of the process.
Thank you in advance for your time and help with this, I really do appreciate it!
