What are you trying to solve here Wil ?
I think mentioning who is your service provider will be a good starting point.

In this particular case I would diagnostic the transmission by using SMTPDIAG from Microsoft.
This tool is free to use

Just expand the file on your drive. Open a command window and point to the folder you expanded it.

Then type:  smtpdiag -d DNSSERVERIP /v

The first is your email address
The second is your destination email address
the third "-d" is the DNS IP used to solved all MX Queries
The last "/v" = verify and returns all details for each steps

You'll get a result of of this test. Copy it and paste it here.
So this way you'll have something to work with.

Also try to be as specific as possible. In one of your message you say that emails are bouncing back and in the next one, you say it doesn't. This will really help me to help you ;-)

All the results will output at your command window.
You don't need to run SMTPDIAG on your exchange server in order to perform a diagnostic.
But you need to launch it from the folder where it's located.
